Beta 4

Beta 4:

-Start position randomization of the vans now works again. The very first race should still have red on the left side and blue on the right side, for clarity.
-A "honk if ready" prompt is now shown at the start of the tournament while the controls are shown on top of the screen. You can also switch straight to 1st person view, before the race starts. (I'll try to make this a bit prettier in future versions).
