Wow so many comments about the Benny Hill music. I for one love that Elon Musk's quirky sense of humour. So many people take themselves far too seriously.
I'd have a hard time believing that, to be honest.
But what is confirmed is that he was speeding at the time as well, and after that incident Tesla put out an update preventing autopilot from being set for more than 5mph over the speed limit.
That's not correct. I routinely drive with autopilot set to +10mph over the speed limit.
