Call me uneasy...
If we're moving towards a driverless era (which is a shame - I still enjoy driving), I'd imagine that we're going to go through a dangerous interim first.
We're talking about first/second generation commercialised technology sharing the road with somewhat more meat-derived drivers. Not only is the tech rather new (I'm sure it's been well tested, but....), but these robocars are sharing the road with some great fellow road users.
How about 18 year old Daz in his 10 year old Corsa with lowered suspension, a fart exhaust and a stereo worth more than the car? He's out wid 'is mates, innit? Showing how fast he can drive, darting in and out of traffic. Can our silicon miracle judge the way this guy is driving and keep out of his way?
Or then there's 80 year old Enid in her Fiesta. She's driven (to the shops) for fifty years and never had an accident. She forgets where the indicators are and sometimes stops a bit sharply when she panics as she nearly misses her turn or doesn't see the traffic until the last minute. She'd be the ideal buyer for robocar, but convincing her might be a challenge (she still uses cheques...).
I'm not opposed to self driving vehicles, but I don't think the short term is going to be straight forward and 100% safe.
