IT HAPPENED ON FREEWAY 57 WHEN I WAS ON THE WAY TO WORK IN THE EARLY MORNING. I WAS DRIVING MY TESLA MODEL X, AND IN THE AUTOPILOT MODE. SUPPOSEDLY IN THE AUTOPILOT MODE, TESLA WILL DETECT THE SPEED AND THE OBJECT IN FRONT AND SLOW DOWN OR ACCELERATE. IF TESLA IS TOO CLOSE TO AN OBJECT, IT WILL BEEP AND STOP. BUT IN THAT MORNING, THE CAR SLOWED DOWN BUT DID NOT STOP. AND ALSO THERE IS NO 'BEEP' THE WARNING SOUND WHEN CAR IS TOO CLOSE TO THE CAR. BECAUSE THE VIDEO IS TOO LARGE, I CAN NOT UPLOAD SO I PUT SHARING LINK YOU CAN REVIEW: HTTPS://DRIVE.GOOGLE.COM/FILE/D/11H_PDLKSLG0JARLNKEVF9YTF6WK0HWKD/VIEW?USP=SHARING. ALSO I CALLED TESLA AND REPORTED SAME DAY, I HAD BEEN TOLD THEY WILL INVESTIGATE AND CALL ME BACK BUT IT NEVER HAPPENED. ACCIDENT HAPPENED ON APRIL 29 2019, AND IT HAS BEEN 4 MONTHS. TESLA IS STILL IGNORING EVERY CALL I MADE IN THE PAST.
