SEEING THE VEHICLES A CONSIDERABLE DISTANCE AHEAD OF ME STOPPED FOR A TRAFFIC LIGHT I TOOK MY FOOT OFF THE ACCELERATOR AND ALLOWED THE REGENERATIVE BRAKES TO SLOW MY TESLA DOWN. WHEN I PUT MY FOOT ON THE BRAKES TO STOP THE CAR IT ACCELERATED VERY FAST AND I HIT THE PICKUP TRUCK IN FRONT OF ME WHICH HIT THE CAR IN FRONT OF IT. THE AIRBAGS FAILED TO INFLATE. ALTHOUGH THERE WERE NO INJURIES THE PICKUP DRIVER IS SUING GEICO FOR NECK INJURY. THIS WAS A VERY FRIGHTENING SITUATION. MY CAR SUSTAINED SEVERE DAMAGE AND HAD TO BE TOWED TO REPAIR. IT WILL TAKE AT LEAST 30 DAYS TO REPAIR. THE PICKUP ALSO SUSTAINED CONSIDERABLE DAMAGE. THE CAR IT HIT HAD VERY LITTLE DAMAGE.
