> Every single pilot has practical first-hand experience with unpowered landing
Considering many people can barely handle driving normal cars correctly, the number of average flying-car consumers that will have airplane pilot-level training, knowledge, skill, and maintain sanity in emergency situations like unpowered landings is minuscule.
I thought we were speaking generally, about today's planes, with today's pilots. However, you might be interested to learn about gyrocopters, which have the interesting property that, if the engine dies, or the pilot is incapacitated and releases the throttles, it will land automatically, by pure aerodynamics.
