 - Unstuck idea: make the body non-rotating for a while?
 - Map4: fix top bottom corner, making the curve is too hard -- either add ramps
   on wall or shift the down ramp further.
-- CP gets often missed, would be cool to increase its radius, but also hard.
-  We would have to be checking 8 cells instead of one, but even then issues
-  would appear with multiple CPs next to each other (returned CP_TAKEN event).
-  Maybe at least make the CP model smaller? (make the diamond diagonal)
-- Fix weird reversing.
 - Try doing the bouncy car body? Just keep a point and its velocity, change
   its velocity by a proportion of car's velocity change (this minus prev.
   frame), then offset car body by this. However we'll also have to transform

 - MAP4: one triangle in top section is missing!

 - Try to mess with car weight? (has no effect without any joint-joint coll.)
 - add ifdefs that change car color?
 - Try progressively slower steering?
