I'll be happier than anyone if there's a simpler way, but the problem is detecting key presses as individual events. I believe that onButton/Key events will be added in the next version, or at least before SPIV; that'll make things a whole lot easier... but I'm more excited about the ability to detect what onTouch is hitting. For the next motorsketch, I'll (hopefully) be able to add AI opponents that follow routes through the track, attacking each other and the player, along with a lap counter!
