Since it's been mentioned that GT drivers move from one side to the other on straights - that's unfortunately a problem with Laguna Seca. The three fastest straights (if you can call them that) are bent and the natural racing line takes you across from one side to the other.
Even when you check every couple of corners where other drivers are on the track map, a) you don't really see which ones are prototypes, and b) the sheer difference in speed between the two classes will mean that every once in a while you get surprised by a prototype coming out of nowhere. And if you're just moving to the other side of the track to set yourself up for the next corner,
and you see a car approaching in your mirror, sometimes you really can't tell the intention, if they want to go through on the right or left. If you continue on your path crossing the track, you might take them out, and if you steer back to the side you came from, you might take their chance to make a last second dive to the other side.
Anyway, this having been my first WSC-race, I think I managed quite alright - had only one bump with a PT and luckily didn't get any damage. (nor was it my fault, I think
)
Eiger will be interesting though in terms of PT-overtaking.
