Hi again!

Currently making a racing game;

I have a question: How do i code it so i know if the player is going
in the "wrong direction", so i can display "REVERSE!" on the screen?

And for the other cars (neutral), are paths a better option for them
or those "robby the robot" AIs?

if you know some racing tutorials, it would really help me if u posted them.

Thanx for ur time!
