  "account": "On the evening of Saturday 15 February 2020, during Storm Dennis, a 400-year-old oak fell across the A31 at Sturminster Marshall, Dorset. It hit two Tesla Model X cars going in opposite directions. Laurence Sanderson of Brentwood, Essex, was driving wife Anna and three children to a half-term holiday. He told the Mirror the car was on Autopilot, the emergency braking kicked in and the trunk landed on the bonnet. The other car, a Tesla loan vehicle driven by Josh Whitelock of Wimborne with Kitty McConnell and her mother Julia, also stopped suddenly. Whitelock told the Bournemouth Echo he was not sure its automatic brakes were enabled. Anna Sanderson had two black eyes and bruising. Nobody was seriously hurt.",

He told the Mirror the car was on Autopilot, the emergency braking kicked in and the trunk landed on the bonnet. The other car, a Tesla loan vehicle driven by Josh Whitelock of Wimborne with Kitty McConnell and her mother Julia, also stopped suddenly.
