xkcd #2940: Modes of Transportation
Title Text:
My bold criticism might anger the hot air balloon people, which would be a real concern if any of them lived along a very narrow line directly upwind of me.
alt-text:
A chart that categorizes various modes of transportation based on their practicality and danger level:
Zone of Practicality:
- Trains
- Airliners
- Boats
- Walking
- Cars
- Scooters
- Bicycles
Zone of Specialty and Recreational Vehicles:
- Motorcycles
- Helicopters
- Light aircraft
- Go karts
- Skateboards
- Rollerblades
- Skis
- Unicycles
- Sleds
- Bumper cars
?????:
- Hot air balloons
“Hot air balloons are the optimal mode of transportation, if your optimization algorithm has a sign error.”
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)
https://www.who.int/news-room/fact-sheets/detail/road-traffic-injuries (1.19 million people every year die on the road)
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.
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. :)
Just check the stats https://en.m.wikipedia.org/wiki/Aviation_safety#Transport_comparisons
From your own source:
So I guess this is the point you are trying to make?
You can argue that "per person miles" is a better metric, but that is completely orthogonal to their initial claim.
