Best way to animate and move pawn class without input?

I have this scene in a street with moving cars, where the player is driving one of the cars in first person. The cars are all fully rigged, and prepared as a pawn class. The problem is, I can only control the cars by using input. If I try to make the street look busy with pre-animated cars (using matinee) the wheels don’t turn or rotate.

So my question is, what is the best way to make pre made animations for busy streets etc using rigged pawns? Should I be using matinee for this? Or should I go for the AI Behavior Tree?
Sorry if this is a common asked question, but I tried to search and I’m not sure what keywords to use for this specific issue.
Thank you
