The male driver of a Tesla car that hit 12 other vehicles at high speed had alcohol in his blood, according to police. He was uninjured.

Police found the blood alcohol level in the Tesla car driver was 194mg per 100ml of blood and were waiting for a doctor's confirmation on the blood alcohol level before charging the man with drunk driving.

Initially the man was charged with reckless driving causing property damage, police said.

The multiple crashes happened at about 3.20am on Saturday when the speeding grey Tesla car hit six cars and six motorcycles near a restaurant on Mitraparp Road in Phitsanulok. No one was injured.

As the driver's name was withheld, police admitted that he was an advisor to the Phitsanulok police affairs committee. The station chief said that the driver agreed to compensate all damaged parties.

Arthit Sriputhorn, 35, said the incident occurred when the restaurant was crowded and fortunately his elder brother, who ran the place, parked a vehicle in a position that protected customers from the speeding Tesla.
