Not much effort was put into this, as I just wanted a deathless run.
Surprisingly enough, this is one of the 3d driving games thats very easy to optimize. Getting a straight line is simple, and the only routing involved is knowing what stunts are worth doing and keeping your score good enough to proceed. You get raided off the bar. So a route would just be a string of Red and Green. I haven't figured out the optimal path though.
