Why do we have to wear seat belts in cars?
<|assistant|>
We have to wear seat belts in cars to keep us safe while we are traveling in the vehicle. Seat belts are designed to keep us restrained during a crash or sudden stop, which can reduce the risk of serious injury or death. Wearing a seat belt also reduces the risk of a passenger or driver being ejected from the car in the event of a crash.
