Help plz. ai cars aren't collidable

I just downloaded the Free version with only the 1 pickup truck.

I can spawn an ai vehicle through F11. I check the box next to "isAIControlled". I hit F11 again to play and "Control-T" to select ai mode "Chasing Player". The ai car however won't respond and I can drive right through it like it isn't there. Also, if it is above the ground it just floats there and won't drop. It's not that I forgot to hit "J" again because I can move my car, however, if I hit tab I can't move the AI car.

I noticed if I use Control-T again it is always reset to "Player". What am I doing wrong?

 

Nothing. I think the demo doesn't have AI. If you don't have any issues running the game, then I highly suggest you buy it because IT'S SO FUN. (On a bun)
