24 hour after taking delivery, operating on Full Self Driving on a residential street at 25-30 mph, the car struck a landscaping trailer parked on the right.The tailgate of the trailer was down and the car struck the left rear upright post of the trailer causing significant damage to my car. No automatic breaking occurred: the car struck the trailer at full speed. The collision alarm sounded just as the vehicle struck the trailer, not before. I requested vehicle status info form Tesla, but the video stops well before the collision and I can't decipher the rest. But I can send it to you if it would be helpful,.
