Use the arrows to rotate your car.
The [D] and [C] keys move you forward/backward.
The [TAB] key changes your view from outside to inside the car.
The different colered lines on the map represent lines that had to be fixed inorder to display properly (clip debugging). It doesn't work perfectly, there's always two lines missing from the grid. Also, the car orientation is a little wonky when rotated up or down. Hopefully it won't take me much longer to fix all these bugs so i can turn it into somthing useful, or not... =)
