Not sure if they asleep or doing this for kicks as the officer claims the vehicle started to accelerate from about 140 to 150 once they put sirens on.
Regardless a Tesla in autopilot mode checks for active driver supervision. Would you mod or hack your driver assist car to be fully autonomous and then you and your passenger recline right back or sleep while it drives 140? I wouldn’t trust it even on the Autobahn or US interstates. One Tesla in the states driving in autopilot mode hit a concrete barrier for an off ramp at highway speed without even braking and killed the driver.
