Car "Jitters" until player sits in it

I’m currently working on a basic car system for a game.

My issue is this: Whenever a new instance of the car is generated, it tends to “jitter”, causing it to move to a offset position. This “jitter” is only corrected after a player has enter the car.

I haven’t tried much, but I don’t know where to start.

In my opinion, this might be caused by clipping parts. If the car was inside of the baseplate a little bit, it could cause it to jitter around.

If this happened to me, I would probably solve it by making it so that the car would be anchored if there was no player in it.
