The driver of an Audi Q7 in London has wrecked a series of expensive exotics while speeding down a street.

The Telegraph reports that the driver of the Audi SUV was allegedly chasing a Porsche down Moore Street in Chelsea and lost control. CCTV footage from one of the houses on the street shows the driver lose control of the SUV moments after jumping over a speedbump.

Initial contact is made with a McLaren 12C which was parked on the side of the road. The Audi then slams into a Porsche Cayenne and a Bentley Bentayga. The force of the crash forces the Bentayga into a Porsche 911 Cabriolet and what appears to be a convertible Audi. According to one local resident, she is the owner of the McLaren, Porsche Cayenne, and Bentley Bentayga damaged in the crash.

“I really thought there had been some sort of explosion, like a helicopter coming down,” resident Summer Haider said. “The driver got out. There was blood coming from his head.”

According to another local, the male driver of the Audi emerged “dazed and in shock” from the crash and was covered in blood. He reportedly told the resident that he was chasing another vehicle that had crashed into him.

A police spokesman confirmed that authorities are investigating the crash.

“Police were called to Moore Street at 0031hrs on Monday August 5 following a collision between a car and number of parked cars. A male driver and passenger from the car involved were taken to hospital for the treatment of head injuries,” they said. “Their condition is not believed to be life-threatening. The driver, however, continues to receive treatment for serious head injuries. All of the parked cars were empty at the time of the collision. No arrests have been made. Inquiries into the full circumstances continue.”
