What year was this? I had read that most (if not all) cars since the early 80’s were made with a safety feature that if you could even get the thing in park while moving over 10 MPH (and that was a difficulty in itself because the pin wouldn’t settle into the Park position while it was spinning), that it would just sling the pin back out and it would be idle in neutral.
The year would have been 1990,1991 or 1992...in Wells, MN. I remember because we competed against them and one of their key athletes was in that crash.
