It is always going to be a challenge.
However there are millions of stupid things done by human drivers every day. At least with autonomous systems there will be an update after each one that will stop it happening again in all such systems/vehicles. That does not happen with human drivers.
My car has a full 'self driving' capability (not a Tesla and I think it's better than a Tesla but then, I am biased) which I tend to use on motorways when the traffic is moving well and, there's not too much of it about.
Today, I have just driven up the M5, M42 & M1 and witnessed at least 7 stupidly idiotic driving actions all of which were dangerous, including the old tail-gaiting then swerving into the middle lane, foot to the floor and back into the outside lane barely inches in front of the lead car who was doing around 77mph anyway.
Today, I've had white van man & SR driver about a foot from my rear end and this makes me feel very pressured even though I was, at that time, doing 80mph - my car will do 0-60 in a little under 4 seconds & has the power to leave them behind in a cloud of exhaust fumes but, that's not the point, and it's not why I bought that particular car - if I accelerate to get away from them (it's not always easy to pull in) I will shift from 70mph to 95mph in less than 3 seconds - and then it's me driving dangerously and, me getting 6 points if I am caught.
These days, I prefer to drive at a steady 65-70mph on motorways but it's often just not possible.
Well, that was a bit of a rant - sorry
