NHTSA Complaint #11509918 — 2017 TESLA MODEL S

Since full self driving, beta has been turned on my car no longer slows down when I reduce the speed or when it encounters a lower speed limit sign, which it will read the speed limit. Prior to this when I decrease the speed or it noticed a decrease speed limit sign. It would use regenerative braking to slow the vehicle down. Now it’ just coasts , and actually sometimes maintains power at a high speed. There are times from going from a 60 and then to a 40 and then to a 30 mile an hour speed zone where it will continue to travel at 50+ miles an hour through the entire speed zone without slowing down which it did not do before FSD beta was active.I have to disengage the full self driving in order to get the car to slow down
