My tesla model Y was driving on FSD (full self driving) and just did hard full stop brake at a traffic light and brought the car to a complete stop even when the light was green. Both of toddler kids in the back got pulled jolted forward where the seat belt hurt them. This stopping was random was unnecessary as no threat of other cars or the light was present. Luckily no one was behind us or they would have rear ended our car causing a serious accident. This really left my children in shock.
