NHTSA Complaint #11452482 — 2020 TESLA MODEL S

The Tesla when driving at 35 mph on AIA at or near the speed limit frequently has quick sudden phantom braking and acceleration. I have analyzed and believe I know the reason. There are many driveways. When cars enter or exit, these phantom braking events occur. Most often when another vehicle ( in front of the Tesla )enters a driveway and is moving away from its lane, even if its tail light is in the bike lane (which is a painted narrow lane on the right side of the road) the Tesla will suddenly brake (flashes simultaneously a red dashboard image for following too close and then accelerate). At the instant of the following too close warning the lane in front is totally clear. It happens so fast that if cars behind are not being attentive they close too close to my vehicle and then set off a warning on my dash. Similarly if on a multilane road and an accelerating car cuts in front of me too close, the cruise control sees the object without considering its acceleration, and suddenly brakes and then as the car in front accelerates to create more distance , the Tesla accelerates suddenly as well. Further, the tesla system invokes more rapid changes in speed - both deceleration and acceleration - than a good human driver would invoke as humans register the acceleration of the vehicle in front of them. In fact humans would curse the other car more often than brake. One other comment: Tesla has an outstanding feedback system between vehicle and headquarters and their system has been behaving better than a 2020 S Class Mercedes comparable one that I have also been driving. Tesla feedback from customers is not even available. I know this is a business aspect - but I believe they would improve their system if they had a way get the feedback I just gave you. But they do not.
