A driver of a Tesla car in Germany has blamed the car’s autopilot feature for an accident in which the vehicle crashed into a tourist bus on Germany’s autobahn outside Hamburg on Thursday.

The bus had been trying to maneuver into the right lane of the BAB24 motorway when it was hit from behind by a Tesla car belonging to a 50-year-old man from Brandenburg, authorities said.

Tesla has denied the claims that its autopilot was to blame for the crash.

The driver of the car was treated for minor injuries and none of the 29 bus passengers were hurt. This is just the latest in a string of incidents involving autonomous vehicles. Earlier this year, a Tesla self-deriving car was involved in a fatal accident. Another accident in China involving a Tesla claimed the life of a young man, last week. That case is still under investigation.
