Btw, when exiting the pit on practice in a lazy way, by going over the other pits in a straight line the car shakes violently in a zone after the flag post to the right (tested with a low car like the DRM Capri). I think this was already present in the 1.xx. Is the cement completely uneven in there? Thanks!
The pit lane is on a slope and the garages are staggered. You can see it quite clearly in photos like this one...
I guess the yellow markings are there for a reason
