Why does a fast car slow down if?

Due the inertia in motion, car will move slowly forward until the resistance stops it.

What causes a car to stall?
This results in the forward creep. If the force stopping the car exceeds the force accelerating the car, it will slow down. If the clutch is engaged, the engine speed will slow proportionally with the car speed. If the engine speed is too slow, it will stall, often with a sudden jerk.
Why does a car keep rolling at a constant speed?
As the car begins to turn, both wheels want to continue rolling at the current speed in linear motion due to conservation of angular momentum. If the wheels are being driven by the engine, then the torque is equal to rolling resistance on both wheels so both maintain a constant speed.
What happens if you turn at too high of a speed?
If you’re not very good, you’ll try to turn at too high of a speed. When the required forces exceed the maximum grip of the tire, they slip and the car spins off the track instead of following the tight radius you selected. Not the answer you’re looking for?
