Hi! The ramps only work if you have enough impulse (you're supposed to use the turbo before and through the ramp), or they can serve as a stopping point so you can spin the wheel without the danger of crashing on a tree. The wheel is supposed to spin when you press Alt or the Right Trigger in controllers (I'm still updating the page so maybe that info wasn't available when you tried it). I'm still fixing bugs, but that should work now. If you happen to try it again and it still doesn't work for you, I'd appreciate the bug report. Thanks :)
