hmmmm, Kinda cool except thats just darn right shitty having Ice permentantly.

first thing that pops into my head is SP bots driving just set them target paths to each 'Race' target and so on and have a switchable BSP and script it so when you hit the right click on the hog, it swaps the burrent BSP to a BSP with the same model but different ground properties (ice) so you 'drift' round corners. But thats just my first impression theory, probs cant be done, although i know bsp swapping doesnt sync online.
