Not a problem, C.A.R., I've already made some [crappy] videos and put them on Youtube and Google Video if you're interested. Those weren't consistent at all, but one or two of the slides have all four tires visibly slipping. Technically, the front tires on my car should always be slipping: they're hard plastic. But since I'm trying to fight skeptism here, I have to make sure my next video makes the front tire-slip blatantly obvious, right? I will try my hardest.
I've improved my consistency lately (I used to drive sitting down on the floor... standing up makes everything easier) so I'll update you ASAP (Friday should be possible) with a good video clip, with all four tires sliding around a marked apex.
Edit: Somehow damaged the FETs in the car... there's no forward. Give me a few days. 2/12 maybe?
