i'm beginning to think that the biggest problem may now be legal.
with a driver there is someone to get a signature/payment/paperwork whilest a driverless vehicle would need something else.
who's responsible for damage inside the back of a truck when it made 3-4 deleiveries?
how easy would it be to stop and steal the contents of one of these vehicles if it can be stopped on a quiet road with a rolling roadblock?
my brother has done 90% of his work on the road in many service/delivery jobs. he reckons at least here in ireland there will always need to be somebody on board to load/unload/handle paperwork/report problems . or if not need to be it might for a long time be cheaper to be.
