Seat belts?
Also, what's with the hump on the front passenger floorboard?
Basically go out and drive int he country at like 30 mph and hit the brakes quick...you dont even need to lock them up just hit the brakes like a deer ran out in front of you and I bet the belts will lock up
twort is correct, the hump unde the passenger's leg area is for a catalytic converter.
