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.

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