Re: "Having a level 5 autonomous vehicle would be very nice indeed."
"Pity THEY DO NOT EXIST"
Shame that no research is being done then..
Oh wait a moment, there is shed loads of research being done, to the point where we have vehicles on the road that are capable of a very significant proportion of the required driving.
Pretty sure that even just getting a car to drive the motorway segments (which are by definition relatively easy) would be a vast improvement to the safety of driving at either end (certainly would improve my driving as I left the motorway if I had just had a few hours rest instead of constant observation).
