On a couple of occasions, typically on bright, sunny days while driving on Autopilot on the interestate, I've passed underneath an overpass and found that the Tesla autopilot system misinterprets the dark shadow cast onto the highway by the overpass and immediately initiates a braking maneuver, slowing the car by about 10-20 mph, and disengaging the autopilot.
When this has happened, it has typically been in relatively light traffic, but I am concerned that if it happened in a heavy traffic situation it could easily initiate a rear end collision. After all, following traffic would not expect for you to put on the brakes when you're driving 70-80 mph just because you're driving under an overpass.
I'm sure I'm not the first person to notice this. I'm curious to learn how other people deal with this situation and what steps Tesla is taking to address it.
