Have to wear a UK hat for this one - we have form with the Red Flag Act
Locomotive Acts - Wikipedia
My dream is I will go to sleep in my car and wake up at my destination, without relying on a human to drive me. This may happen eventually but I can't see it happening very soon.
Given the fact that legislation is always behind the curve on technology and the limiting factor at the moment appears to be legislation then it may take a while.
Considering the recent active UK clamp down on electric scooters, illegal to use on anything other than private land, along with e-skateboards, not directly legislated against but the police have been handing out cautions to people in London recently. Properly insured licensed etc to avoid complete chaos, these make sense as a form of transport. But rather than show a progressive attitude or implement sensible trials, our government appear to have the red flag act mentality. Personally I think the hire & go monetisation attempts of e-scooters causes a lot of problems where they have been allowed a foothold. Private ownership means you'd have at least some respect and not be so inclined to throw it into a canal.
It's all step at a time stuff - the more confidence is achieved the more things will be allowed, the polluting liars (Incumbent manufacturers) will lobby against this sort of thing as they have been caught napping and would rather lobby and put out concept adverts to avoid portraying themselves as anachronistic environmental criminals.
In the meantime the insurers will likely deem non-intelligent cars appear to be less safe as they are wholly reliant on the person in the driving seat. It's a hybrid system, the car should make things safer and the driver is wholly responsible in a legal context, as far as I am aware at least.
I bought FSD in the same context that I got TSLA shares and selected the tow bar option, I'm supporting the cause hoping it will come good one day.
