The boss of Tesla's Autopilot programme has just quit. Probably not connected but it is on the back of a couple of accidents including, tragically, a fatal one.
So, not a good idea to put too much faith in the system right now.
Like this bloke from Nottingham did:
The BBC report on how Bhavesh Patel moved into the passenger seat after putting his car into autopilot while at 40mph on a motorway.
Patel said he was the "unlucky one who got caught", the court was told.
That implies others do it regularly without getting caught.
I doubt that, but if it is true, then hopefully his 18 months driving disqualification, 100 hours of unpaid work and Crown Prosecution Service costs of £1,800 will put them off.
Especially as it is so easy to spot a Tesla driving under autopilot by the blue lines and circles emanating from the car:
