Dumbest Thing I've Done in a Vehicle?

Dumbest (non-sexual) think I've done in a vehicle?

Glad "non-sexual" was specified....

Memorably, opening up the 1970 Mustang Mach I (351 4-onna-floor Herst shifter - I used to know what all that meant) on the turnpike from Tulsa to OKC.

Slowing down near OKC, the HiPo picked me up at only just-under 90mph. Lucky me!

Got that out of my system.

Dumber things probably involved alcohol, unzipped pants, and fatigue, if I could remember any of them. I seem to recall a 1400-mile weekend round-trip to visit a girl who, turned out, wasn't interested...
