Re: Can we have them
That will enable testing of driverless car in only situation they are wanted - saving someone from the dread designated driver role.
I agree, that is the primary use case, however... there are others.
Disabled people who cannot currently drive might enjoy the greater independence self driving cars can bring.
My personal most frequent use case would be to take me to work while napping in the morning, and bring me home again in the evening while I get in a bit of gaming time, or study something, or maybe nap again if it was a 'long lunch'.
