How to Add Enemy for my Car Game ?

I was confused for this problem, anyone can help me with an example?

I think you must search on google/blenderartists for car AI. I think this is what you’re searching for: There is a download link in the description so maybe you can take a look how he made it. Good luck.

Enemy sounds a bit too much- does he really attack you and try to kill you? I’d reather call it opponent:D
