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.”
Just check the stats https://en.m.wikipedia.org/wiki/Aviation_safety#Transport_comparisons
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?
