A car has higher momentum when traveling faster because momentum is the product of an object's mass and velocity. When a car is moving at a faster speed, it has a higher velocity, resulting in a greater momentum due to the increased product of mass and velocity.
Yes, a car traveling along a curved path at constant speed does not have constant velocity since velocity is a vector quantity that includes direction. However, the magnitude of the car's momentum (which is the product of mass and velocity) can remain constant if there are no external forces acting on it.
Regardless of the direction being travelled, any object on the move has a positive velocity, even if it is moving backwards, because velocity is the measure of the rate of movement in a given direction. Compare: A car is traveling forwards on a highway at 100 km/h. How fast is it travelling? If it turns round (or even it doesn't turn round, but just reverses) and travels at 100 km/h, how fast is it travelling? The answer is 100 km/h in both cases. (But reversing on a highway and travelling at 100 km/h is not recommended!)
Depends entirely on your frame of reference! If you are in a car traveling along side it at 50 ms, the car will appear to be standing still. If you are going the opposite direction at 50 ms, it will appear to be traveling at 100ms.
One example of Velocity is that if you are running in the same direction, your speed and velocity is the same. But if you are running AROUND the track, your speed is the same but your velocity is changing.

The wheels only appear to spin backwards.
yes, the car would have to be traveling at a faster velocity though, assuming that the car weighs less
Speed. (NOT velocity.)

Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
