Why does stopping a vehicle you’re in cause you to jerk forward, even though motion is supposed to be relative (and the vehicle isn’t moving from your “physics” perspective)?

You are not the car. You are an object in the car. When the car stops, the objects do not.

That’s a simple explanation, but a simple problem. Relative motion doesn’t play into anything here. The car and the objects are separate entities.
