The driver won't have to be vigilant or even awake for the whole time, only in emergencies. I'm assuming the car would stop or slow down automatically in case of any problem and notify the driver. Good point on the pilots, though I always felt that it's unnecessary for them to stay awake (especially on cargo planes). And it looks like many do fall asleep inflight: http://uk.reuters.com/article/2013/10/08/oukoe-uk-britain-pilots-sleep-idUKBRE98Q0L620131008 http://uk.reuters.com/article/2013/10/08/oukoe-uk-britain-pi... Truckers, on the other hand, need to be alert all the time, falling asleep for even a few minutes can be catastrophic. I'm mostly hoping for fewer human drivers - two drivers/technicians should be enough to drive a whole convoy of trucks between cities/countries.
