I had a close call when I was ~16, this was long enough ago I'll put it on here, back in late 1995.
So I was driving my 81 Regal, going down a country road. It was a long straight empty asphalt road. My regal at that time had a 412 CID SBC that burned oil, stock crank, stock iron heads, headers, with a Holley carb. It also had a used TH400 and an old 12 bolt out of a 72 Monte. Sometimes I would just let it coast. So I ripped it through 1st, bumped second, and let it eat until I would need to shift to 3rd, then I bumped it to neutral at about 90 MPH so I could just coast for a while.
Only I didn't bump neutral, it was a column shifter and I went one too many! I shifted into reverse going 90 MPH!
I was immediately slammed forward into the seatbelt while I fiddled trying to get it back into neutral. I got it back into neutral after a second or two, only to look in the rearview mirror and see two streaks of smoke with two black marks under them, you travel quite far in that short time at that speed.
I immediately thought, the engine is still running, but I had to break something. It never stalled, so I coasted to a stop, still no one around. Tested reverse, tested forward gears, revved the engine a little. Nothing seemed wrong. I drove that car for over a decade with the same trans and rear axle parts, still worked when I removed them.
But I don't recommend trying that, I could of been in the ditch flipping over and over and dead just from bumping one notch too far! Learned a big lesson that day, I had done that a lot of times, but I didn't do it anymore. Eventually I got a ratchet shifter, for safety, and fun, at the track.
