Though I haven't driven such an equiped vehicle as yet (atleast I think I haven't), I'd rather have direct control. I suppose electro-mechanical devices coupled with computers can expand the possibilities - the flying wing bomber's too unstable to fly otherwise. There seems to be an air of compensation.
Added complexity - certainly, as controlled operations seem to make-up for what's lacking in physical design.
The pilot's turning into a co-pilot? - good for those that try to talk on the cell phone, put on their make-up or play with their hair, eat, read, fiddle with the radio or stuff in the vehicle...while they're driving.
What happened to the good old utilitarian vehicle? The owner friendly sort that doesn't require computer interface and random software upgrades and expensive one-use only tools???
