Hi Quico could you please send me your email address so that I can send a replay.
The best example of what I have found is on the exit from Le mans. I was trying to run just one wheel on the righthand curb but got it wrong and ended up with both wheels outside the curb. My left wheel is running just outside the curb when it appears to hit something solid.
Cheers
Clive
