I know you're probably right but when I've decided what the distance/severity of a corner is I don't find my perceptions changed when I see it at speed. Yes on stupid long straights like the one at Baie where I hit 205kph before I backed off, My co-driver was counting down by hundreds for a KM cause I was sure I'd miss the L at T at the end. But Jemba scared me. The distances just SEEMED so wrong and I could not go fast on them.
