Answer 1

The car is big and heavy, and needs the engine running at a high enough speed to a) get it going and b) keep it going.

Engines have a power phase and a relaxing phase. So when youre pottering along the road, the car is going fast enough to keep the engine turning over it its relaxing phase.

But when it’s stationary, the engine will get the car going very briefly during the power phase but during the next relaxing phase it will just….stop. There’s nothing to keep the engine turning over until the next power phase because the car is still.
