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