Re: The Man In The Rubber Mask.
"Today if a driver cannot be identified the owner (registered keeper) is ultimately liable. Why would you want to change this legislation if it would still work perfectly?"
Because it wouldnt work perfectly. That current legislation exists because it can be assumed that the cars owner would know who is driving it at a given time, if they dot know (or wont say) then they are given the penalty as it is assumed that they are either lying or it was them driving.
However that process is an exception for when the actual DRIVER cannot be identified not the default route that is taken. Besides, we WILL know who the driver was.. it will be Alexa, Cortana or Clippy... So why should we take the blame for something done by a piece of software?
Lets look at a scenario using your idea:
You own an autonomous car.
You maintain that car as per the manufacturers recommendations.
You go on a night out with some friends and end up miles from where you parked so you call the car to come and pick you up.
On the way to collecting you the (Driver-less, Passenger-less) car fails to detect a speed limit change and goes through a camera.
Remember, you maintained the car EXACTLY as you should have, installed all of the updates and ensured that all sensors were perfectly working and it still triggers a camera... Are you saying that YOU as the owner should be liable for those points?
I suspect that as autonomous cars become more ubiquitous we will see fewer and fewer speed cameras anyway as there will be less of a need for them so this probably wont be an issue in 15-20 years anyway.
