Cool. I figured that it had a built-in safety override or something like that. It acted like it was in Neutral.
Unfortunately it's not a cool or funny story at all on "how" it happened. I wish I could say it was my girl who did it with her shoulder or waist, but that's not how it happened.... Some fat ass at my work apparently can't park next to - and walk between - my 4R and his ride. So he turns my passenger side mirror "in" so he can get by. It happens about 2x/wk on average. Well, this one time I didn't notice it had been turned in until I was on the highway. But I NEEDED the mirror because it was rush hour, so I rolled down the window, took off my seatbelt, leaned over, and popped the mirror back in place. Meanwhile I must've hit the shifter by accident. Got back in place and noticed that I was revving the RPMs but doing nowhere... then also noticed the shifter was in R. Thanks FatAss.
