“The seatbelt latch for the rear seats retract into the body of the car and then can't be used. This happened twice now and each time a rear seat occupant had to ride without a seatbelt . The latch later had to be retrieved with a hooked wire and needle nose pliers. Other vehicles have a button in the belt to prevent it from retracting or the opening in the car body is too small to allow the latch from retracting in.”

“With the introduction of self driving features new passernger saftey regulations are needed. My car , an added feature, is distronic safety system, self drive mode. When the car is at acomplete stop it will sense if some is about to rear end you. The car completely locks down. With impact the passengers in the vechile take a full body impact. The current seatbelts do protect the left side of the body but the right side gets sever damage. Harness seat belts such as race car drivers us or children car seat would minimize right body injures. …”
