Adding a data point to the pre collision avoidance... I've had 2 full track days at High Plains Raceway and no issues with windows up or seatbelts pretensioning or any other safety systems intervening. I'm always in M mode Track and I have the M Drive Professional package with HUD.
Running lap times around 2:03 and if you're familiar with HPR, that is pushing pretty hard in the M3.
