I am absolutely at a loss as to what is wrong with my program at this point and how in the world to solve it.

The AI car is doing crazy things. It moves quite happily along its own path, but as soon as the map starts scrolling, the whole thing goes up sh&t-creek and the paddle has already sunk.

At this point I am hoping that 'Tarviathun' is going to be able to help as he appears to be my only hope!

Anyone else that fancies a try please feel free to download a copy of the currently 'broken' D2 from http://members.gamedev.net/ols/zip/tiles.zip, and laugh at the amusing movements that the AI car has decided to partake in!!
