I went down on a run that I expected to be very empty and tested it then. I think it was early on a Saturday or something. That way there were fewer people to piss off.
But I can't honestly say that I would as daring if I was driving an R8.
Maybe check some other high-end sportscar forums and see if anyone has any input? Come to think of it, I've never seen anything especially high-end on any of those runs. Wonder if there is a reason for that.
