An astute commentator on the technology Sub-Reddit pointed out that commercial aircraft fly on autopilot but active involvement of pilots is expected. No one ever contemplates the contrary.
The autopilot on a plane has a far less challenging environment than a self driving. Planes do not have to navigate passed other planes within a fraction a second of collision, along with pedestrians and bicyclists.
Planes do not have the follow hyper-accurate maps and turn and swerve almost continuously to avoid a collision as distinct from turbulence or an error that is quickly corrected by pilot before any danger is encountered.
As far as self drive cars will go, I think they will be confined to driver assist functions with a driver always having to have his hands on the wheel.
A peculiarity of self drive cars is the brand name of Googleand Tesla are so strong that they have been able to hold off the usual Luddite reaction to new technologies.
Utopia, you are standing in it!

I think we all like the idea of a self driving car. Will it every be practical? I for one doubt it. Thanks for the post.
