I cant believe bicycles and scooters are perceived as more dangerous than cars. They're slower, offer better visibility, and kill way less people.

82

Not only. I live in Norway, where pedestrians have right of way and drivers are extremely careful. Discounting the risk from cars, there's still more personal danger to users of scooters as opposed to cars. If you have an accident on a scooter, you'll get scrapes, bruises, broken bones. As compared to a car, where unless you've really screwed up, you're unlikely to take any injuries at all.

The chart needs a third dimension: danger to you, danger to others, and convenience for travel.

5

I think most normal people can understand the difference intuitively without needing it spelled out.

I just saw a pedestrian get hit by a person on a bike and end up with a concussion. Bicyclists don’t give a fuck about others

Driving a car makes it more likely for your species to go extinct. Infinitely more dangerous than a bicycle.

Microplastics from heavy vehicles scrubbing away their tires is a bigger issue than tailpipe emissions, which is why tailpipe emissions are the only thing focused on with regards to regulatory standards. Can’t have people thinking BEVs are similar/worse for the environment than a small car.

Hit a pothole going 25mph in your car. Hit the same pothole going 25mph on your scooter. I'll come visit you in the hospital after the scooter one and we can talk about how cars are obviously safer.

I ride an electric scooter, all it takes is one crack in the road that I'm less than prepared for and I'm going down hard.

26

That is a good point, mine is the second variety, electric one similar to the ones you see littering any major Urban area waiting to be rented. Although even the largest scooter is still far less safe over a pothole or around a rainy curve than a car, typical accident in the car you mess up the car and get a bruise from the airbag, but a typical scooter accident can be a lot more gnarly.

9

I think most people in the USA refer to the third item as a moped, which only gives you two categories for scooter. Scooter and electric scooter, and then moped and electric moped.

4

I own an electric scooter very similar to the second one pictured (minus the RGB) so that's what I was thinking of.

3

The roads are shit here. So badly cracked that I vibrate violently when I try to ride my scooter over them at like 10km/h. And that's while dodging potholes.

They are more dangerous exactly because of the existence of cars. Cars are a small fortress that makes others less safe while keeping its contents safer. Unless they hit another fortress.

Even if there were no cars, I imagine biking is still less safe than walking. Just like running is less safe than walking.

That only makes sense if you cycle among cars, but that makes cars dangerous, not bikes. If you remove cars out of equation by cycling on pavement or cycle route, the danger is gone.

Pedestrians get hit by cars all the time yet walking is rated the safest.

-6

If you remove cars out of equation by cycling on pavement or cycle route, the danger is gone.

If you remove air out of the equation the danger of helicopters are gone

7

Pedestrians don't get hit by cars quite as much as cyclist, proportionally to their number, because cyclists are right in the street sharing the space with cars, trucks and buses. Cycling on the sidewalk is not allowed, and cycling lanes are often very dangerous. I understand that this chart is talking about danger to the passengers, not to others.

Tell you what, you drive your bike into a car and maybe the concussion will change your thinking enough to make it believable that bikes are more dangerous.

We're not rating danger for the damn planet here. It's obviously danger for the user - that's the one who's buying the product. Why would anyone care about the safety of others over their own safety?

No need to indulge but since you got me thinking about self interest and empathy:

We're talking about me now? No. Of course not. Just like I wouldn't knowingly buy a car whose making process involves some random people being shit inside of. I find hyperbolic exaggerations funny and I like to use them for making a point.

The point was - you don't purchase things for others, you purchase them for yourself. A car can be a major money spender - you buy it because it gives YOU safety, and it's silly to act like you're a bad person for spending your money in a way that benefits you. But some Knights of the Broken Tire are out here pretending like they're damn selfless, like they spent all their house money on housing the homeless not their own family, and like they chose to carry that 2 year old through traffic on a bycicle, not a fucking minivan. Fuck right off with this hypocritical shit. It's okay to want the safety of yourself and your family, that's how the entire world works. You're not gonna get blamed for buying a car, drop the selfless, holier-than-thou act, nobody's buying it.

it annoys me to no end how motorcycles and mopeds are viewed as dangerous, when every single time you hear about people being hurt on them it's because they're fucking idiots who tried to do a backflip infront of a semitruck

8

Horses are technically more dangerous to ride than motorcycles. It’s just that motorcycles attract a kind of people who like doing backflips in front of a semi truck.

2

sure but that applies to everything, if you want to be safe then the only time you should ever be on a road is inside a bus.

8

I'm here to say that if there's snow, skis win on practicality. Almost every winter, there's at least one day when you will have some people skiing to work in Oslo, a city of 700 000 inhabitants, with a metro system. Because when there's 10 cm of snow in the streets, skis are the quickest and easiest way to get anywhere.

4

You can be a skilled rider and still and a fall. More likely is that an unsafe car driver will do something that causes an accident.

-1

Yeah, the joke and alt text are delivered quite nicely.

lemmy.world

The placement of „Skis“ in this will trigger every Scandinavian I know. Should definitely be in the top left.

47

Even us close to Scandinavia get triggered. There aren't that many practical ways to get around at winter. Skis work when feet don't.

6

I'm from the Scandinavian country WITHOUT mountains and with less snow and am as such not triggered.

You don't know me, though, so I guess your statement might still hold true 😁

4

In Canada too. It's not that common, but also not out of place to see people doing their regular commute on skis.

lemmy.today

Technicalities:

Planes are safer per mile but not per trip. One could argue that if people spent the same amount of time in both then it would be far more fatalities on aircrafts.

Cars are technically the major source of danger for bikes and scooters.

also a fun fact, while commercial aviation is very safe, private planes are much more dangerous, being almost as dangerous per mile as a regular car (and you get a lot more miles per hour of travel)

AeonFelisreply
lemmy.world

That already fits with the chart - "commercial aviation" is "airlines" and "private planes" are "light aircraft".

10

private planes are much more dangerous, being almost as dangerous per mile as a regular car

that is because they are operated by semi-competent people who often have less practice then they have in car.

imagine how competent driver you are when you have your fresh license. it is the same with piloting license. and now imagine you are a hobby pilot and can afford to spend in the cockpit 3 hours per month. your skill is not really going to get significantly better. you are probably flying airplane that is at the end of its life, because that is only one you can afford, and there may be no one keeping an eye on you telling you "this is not how we do it, it is risky, dangerous, and you will get someone killed".

You’d have to. Anyone who mountain bikes regularly knows how much work it is to climb some trails with 500% gear range. I can’t imagine the work involved with a single gear to climb on some trails. Brutal.

5

This is probably another reason why unicycles are less dangerous. People I know that do mountain biking end up in hospital from time to time from coming off at speed, speed on most unicycles is probably a lot lower. Though I thought geared unicycles existed?

1

I was joking, but i guess now i know what im gonna watch on youtube next

3

There are basically no unsafe ways to get off of a unicycle. You can fall in any direction and just end up standing next to your unicycle. Compare that to a bicycle "over the handle bars"-accident.

Unless you have pepper infrastructure.

Edit: sorry that's not true, see this from the Netherlands:

Voor het vierde jaar op rij kwamen meer fietsers (270; 39%) dan inzittenden van personenauto's (194; 28%) om in het verkeer. De meeste doden in het verkeer vallen onder ouderen: in 2023 waren 375 (55%) verkeersdoden 60 jaar of ouder. Kinderen (0-14 jaar) komen juist relatief weinig om in het verkeer; in 2023 waren dat er 20 (3%). Het risico om te overlijden in het verkeer, het aantal verkeersdoden per afgelegde kilometer, is het ho ogst voor gemotoriseerde tweewielers. Het risico voor brom- en snorfietsers en motorrijders is ongeveer dertig keer zo hoog als het risico voor inzittenden van een personenauto. Voor fietsers en voetgangers is het overlijdensrisico respectievelijk acht en zes keer zo hoog als voor auto-inzittenden, in de periode 2012-2021.

Translation:

For the fourth year in a row, more cyclists (270; 39%) than passenger car occupants (194; 28%) were killed in traffic. Most traffic fatalities occur among the elderly: in 2023, 375 (55%) traffic fatalities were 60 years or older. Children (0-14 years) are relatively rarely killed in traffic; in 2023 there were 20 (3%).  The risk of dying in traffic, the number of traffic fatalities per kilometer travelled, is highest for motorized two-wheelers. The risk for moped and light-moped riders and motorcyclists is approximately thirty times higher than the risk for passenger car occupants. For cyclists and pedestrians, the risk of death is eight and six times higher, respectively, than for car occupants, in the period 2012-2021.

Those first two are incredibly fit for some niche that is so small that nobody even remembers it exists.

The last one is still more practical than hot air balloons.

I watched a documentary once about the dangers of monorails. The conductor had possums in the wiring. He called the big one Bitey.

Even with heavier propulsion, blimps and rigid airships are completely beholden to the weather as a light breeze can completely prevent landing or cause crashes.

I'm not sure I agree that unicycles are safer than roller blades. But that's probably because I am comfortable on roller blades and don't know how to unicycle, so for me, the opposite is true.

6

As both an extreme unicyclist & rollerblader, unicycles are actually incredibly safe. More safe than a bicycle. The top speed is very slow comparatively, and if you fall... You fall on your feet. Forwards? Feet. Backwards? Feet. Sideways? Feet. If your feet were strapped into the pedals (like rollerblades...) it would be a deathtrap.

9

I suspect that roller blades have much higher top speed, as well as being much more susceptible to small rocks

Trains and planes and others are a bit wonky for this chart. If I needed to take get to work, train and plane immediately resort to walking the entire way (unless get in a car, on a bike, fall just after). So while traveling across the country for a trip may be convenient on a train... Wait, unless I only have the weekend or a short work trip/vacation, because then it would take to much time and be inconvenient. Tried to find an example. Travel to Las Vegas from Nashville. Plane, ~3 hour flight plus let's say 2 hour travel and airport bs. So 5 hours there, 5 back. Driving: 26 hours (each way). Walking: Death by dehydration in desert. Train: not even listed as there was no routes.

It took me too fucking long to figure out what an "airuner" was...

They are also significantly more dangerous than an airplane though. The skill and speed needed to cope with an engine failure is a lot less forgiving and helicopters nearly always spend more time at lower altitude. Also the number of mechanical failures that result in everybody aboard essentially guaranteed dying is higher in a helicopter. Especially vs a small airplane with a parachute (parachute systems on helicopters are extremely rare especially due to altitude requirements)

I really wish the x axis was average distance traveled and the y axis was danger.

I get that the way this graph was designed was for humor and to highlight hot air balloons, but if you’re looking for a safe vehicle for a specific distance, it really doesn’t help out in any way. It probably wouldn’t be safe to drive my car across the Atlantic Ocean.

Edit: oh you meant in the zone of practicality, not the y axis convenient for travel. The zoning i feel is pretty subjective

Looks like only because they're presented as dangerous. Convenience - wise they're still the same. Practicality seems to be defined here as a balance between danger and convenience.

The fact that airplane travel is safer than cars is a myth invented to promote airplane travel. Well, it is not fully a myth, but to get to that result they measure per mile, and that greatly favor airplane travel. If you instead measure how likely you are to die on your next trip, then the dangers of airplane travel will significantly exceed car travel and other means of transportation.

-10
lemmy.world

This is complete horseshit.

Are you aware how many flights take place every day?

Vs

How many fatal accidents pr flight?

The fact is that almost every time a fatal accident happens in a (commercial) plane anywhere in the world, you hear about it. Because if a plane crashes a lot of people die in one dramatic (and rare) event.

Fatal car accidents litteraly happen every minute of every day. Almost none of them go on the news. (Cause reporting them all would be impossible).

Let me also post some sources, since you did not:

https://injuryfacts.nsc.org/all-injuries/preventable-death-overview/odds-of-dying/

https://www.icao.int/safety/iStars/Pages/Accident-Statistics.aspx/ Air traffic: (3187 fatalities over 10 years)

I think you underestimate the number of trips per car per day. Most people will take more trips by car per month than they will fly for their lifetime. In Sweden , a country of 10 million, we have about 150 people killed per year from car accidents, yet most adults travel by car daily. That is millions of trips per day, and only half a death.

lemmy.world

Sweden , a country of 10 million, we have about 150 people killed per year from car accidents

Yes, and how many die every year from plane crashes in sweden?

If we take a relatively big plane (450 passengers) as an example. One has to fall out of the sky every 3. Years to match the car accident number...

3186 deaths over 10 years VS 1.19 million every year.

(This is globally. Sweden and Norway(where i live) will naturally have pretty radically lower numbers then globally when it comes to road safety.)

But look at that air travel number again: 3186. Over 10 years. Globally. Commercial Air travel is fucking safe. Its horrible for the climate. But its safe.

Whatever way you slice those numbers it comes up air travel i safer. Feel free to find actual statistics that contradict me. :)

7

I think I get what the guy is trying to say. Per journey, air travel might indeed end up being statistically less safe (how many times a year an average person flies vs. how many times they drive their car) but of course the question is whether that particular metric is any useful. Surely if you replaced all airplane trips with car trips, more people would die.

This Wikipedia article contains a table, which if true, confirms it:

https://en.wikipedia.org/wiki/Aviation_safety#Transport_comparisons

If you sort it by Journeys, you'll find that 117 people die in an airplane per billion journeys, while only 40 die per billion car journeys. But the article points out exactly what I said before.

Funny example that illustrates how important the choice of metric is, is the Space Shuttle which is statistically incredibly unsafe per journey (17,000,000 deaths per billion journeys) and even per hours (only skydiving coming first by a small margin) but is safer than bicycles and only twice less safe than cars per distance traveled because of those insane distances it covers in orbit.

Edit: Not that I do not know whether the table counts only commercial flights or all airplane/helicopter journeys. And also the statistics is pretty old (1990-2000) and only covers the UK, so you may still be right and commercial air travel in the last decade might be safer per journey than cars globally. Can't find a better statistics.

10
lemmy.world

From your own source:

Since 1997, the number of fatal air accidents has been no more than 1 for every 2,000,000,000 person-miles[c] flown,[citation needed] and thus is one of the safest modes of transportation when measured by distance traveled.

So I guess this is the point you are trying to make?

4

You can argue that "per person miles" is a better metric, but that is completely orthogonal to their initial claim.

5
snaggenreply
programming.dev

Well, what I want to know is "Am I going to die today?". The distance traveled is irrelevant to answer that question. The only reason to add that to the equation is to make air travel look safer.

1

I honestly think you are showing a fundamental lack of understanding of statistics.

"Per trip" is a horribly poor metric. Because there is a fundamental difference between a trip down to the store, or a cross country trip, even with a car. Also it would be extremely dependent on where you are going, where you live etc. etc.

For the discussion to have any meaning you have to abstract it to a metric that makes sense for all people, or else you would have to also figure in where you usually travel, how good a driver you are etc etc etc.

At that point its a completely meaningless semantics exercise because for instance taking a plane to work is not realy valid for me since i live in the same city as i work... Or lets do it the other way around: If i need to go to Spain tomorrow, its safer for me to fly then to drive there. (This is based on your own sources)

2

Very interesting 🤔

And your point about metrics is pretty spot on.

In the end it becomes an exercise in trying to find the metric that best supports your argument.

We have also been jumping around a bit on geographical limitations. And in for instance Scandinavia, the original premise might be closer to real due to better road safety.

I think implying some sort of myth or ruse is missing the mark hard on this subject.

2
snaggenreply
programming.dev

Per trip is more in line with how people think about danger. Like, am I going to die on this trip?

2
lemmy.world

I would think real statistics would be more interesting then peoples emotions when talking about what is actually dangerous.

2
snaggenreply
programming.dev

And the question is am I going to die on this trip? And there the real statistics are pretty clear, cars are safer.

1

I sort of answered this somewhere else but i will reiterate.

Using this metric you are sort of assuming all trips are equal. No matter how short, or long you are assuming the base danger is the same. This means that driving 100 meters is just as dangerous as driving for a whole day. (See what the problem is?)

And if we look at this premise in isolation: "Am i going to die on this trip"? If the trip is 100m, then a plane is probably out of the question either way. And if the trip is to a different country.. then hey, look at that, the sources you cited come into relevance (where pr distance a plane is safer) and you would have to calculate the danger of completing that specific trip in a car VS flying that distance with a plane.

You are generalizing on terms that make no sense, since "total number of trips" in cars include all manner of different scenarios of some times extremely varying degree of danger. So in order to have data that is statistically relevant and in any form comparable you have to choose a different metric.

So to answer the question again "Am i going to die on this trip?" or to extrapolate "should i drive or fly on this trip", if you cant use generic statistics, the answer will be "it depends. You have to calculate danger for the trip specifically".

Trains, scooters and/ motorcycles are convenient for travel? I mean sure, if you never carry anything anywhere and/or you love how every other person in the world smells after they finish their 12 hour shift of breaking big rocks with smaller rocks.
