all cars r provided with seat belts why?

When a car suddenly stops, the car comes at rest but our bodies remain in motion due to inertia of motion. So, we fall in the forward direction.

The seats belts keep us clinged to the seat and do not allow us to fall

when a car suddenly stops ,the brakes are applied only to the tyres, due to inertia (every object have the tendency to continue in uniform motion or rest) the car exept the tyres have atendence to move forward but the car and the tyres and connected very well so the car wont move forward exept a few cm.but the pasesengers are not connected to the car so seat belts are necessary.

thumbs up pls
