I finally got around to trying this tonight on carpet, and I'm a believer! I'm matching my old fast laps, and the car is so much easier to drive. It doesn't do any of those weird spool things you don't realize are happening anymore because you've been driving one so long. Also, I find it much easier to make slight corrections if I take a bad line. I've corrected out of more taps tonight than probably the last year combined.
