> What do we want from self driving cars?

I would say, drive me long distances on the high way. The rest (last mile, city country side) I can do myself. It also aligns with the fact that it is easier to make autonomous driving work for high ways than inside cities etc.

This would make taking an airplane less tempting and as my car can fit the whole family we do not need to fill up 4-5 seats in an airplane and we use much less CO2 per passenger.
