Definietly that time I was on the track in my Miata and hit a (just added, later painted orange) berm, next to a berm you’re meant to hit...and my back top went up...and came back down...onto my glass window...and exploded it everywhere. Pulled the seats out, borrowed a shopvac, taped up the window, and made it back out that day (probably missed my next session.) Not the most fun day at the track.
