I never thought we would see a topic like this for AR but I did get something that is probably rare, so a few others may come soon.

I was too fast in a turn in 4th gear, went straight to the wall and the car turned towards the starting line, coming to a complete stop over the green grass. The (automatic) transmission shifted down quickly to 1st gear and I stayed there, the engine redlining and the car just still. 

(I quit that race - thinking I could save the replay - but went directly to the main menu)
