Oh yes, embarrassing, like driving with the handbrake set, driving with loose lug nuts (a couple actually came off), overreving the engine thinking that the transfer was in hi and only looking at the speedometer, not noticing screech from the engine as rpm must have topped 2,800 (I don't put my headset on around town any more), taking off with outriggers dragging (cranetruck, you know).
When I first drove my deuce home from Camp LeJeune, NC in 1995, one headlight was (later) found to have been installed upside down and that must have ticked off a few people. Driving for a long distance not being able to change into slow lane when passenger side mirror decided to adjust itself. That's when it was an M49A2C and no way to see who or what was to the right of me.
When I first drove the deuce at Camp LeJeune, which was my first time since AIT back in '70, I thought for sure that the transfer was stuck in low and drove around the base a couple of times before realizing that "high" actually was supposed to be that low.
Driving with turn signals on long after a turn used to be a common thing. That little problem was solved with the buzzer gizmo.
The list goes on, all I can say is that you can learn a lot from your mistakes.
