Tesla Driver Charged With Dangerous Driving For Speeding While Sleeping ++ The driver was spotted with the seat fully reclined (most likely sleeping), traveling at over 140 km/h / 87 mph. Earlier in the year, during the summer, 20 year-old Leran Cai was spotted on a highway somewhere between Edmonton and Calgary (by other drivers and even the police) in the driver’s seat of his 2019 TeslaModel S, but he wasn’t actually manning the wheel. In fact, his seat was fully reclined and, by all accounts, the driver was asleep whilst the car was traveling at a speed as high as 150 km/h, driving itself on Autopilot.
