...and apparently all the suspension parameters stripped out for some bizarre reason. The physics simulation clearly uses inelastic collisions, which is wildly unrealistic and why so many otherwise passable 'cars' don't pass the course. Also seems to use a very low coefficient of friction - most of my cars couldn't make it up a two-segement slope.
