Yeah noticed this on the special stage whilest tuning my Veyron (:razz in the rain that there was some jaggies around the car where the spray was kicking up, kindof dissapointed.
EDIT: Also my dreamcar (Nissan Skyline R32 GT-S-T) didnt have the good rumble sound in the engine even after kicking up teh ol' subwoofer i was well dissapoint even a full tune-up worth of what 300K? it didnt sound better just more like a PGO Hot-50 :/
