On the evening of the 16th local time, police in Emnes, the Netherlands, found that a Tesla car was strangely following a slower truck when there were no other vehicles on the highway. They decided to see what happened and found out that Teslas driver was asleep.
Later, the police managed to stop Tesla and wake up the driver with a siren. After investigation, they found that the car was in AutoPilot state. The driver was drunk and asleep, so the police decided to revoke his drivers license.
Tesla said drivers need to monitor the system when using AutoPilot and require drivers to occasionally apply slight torque to the steering wheel. In these cases, police said the driver had fallen asleep with both hands on the steering wheel, which could exert enough torque to prevent AutoPilot from stopping because the vehicle was not responding.
