That reminds me of a serious error I made one day when I was in a hurry on my old Honda 450 motorcycle. I hopped on the bike, and forgot to unlock the forks as the front wheel was pointed into the direction I wanted to turn and go. In the old days bikes had a separate lock for the forks up on the steering column, and the electrical key switch was under your butt, so two separate things, not like today's bikes. So anyway, I fired her up and took off for a couple of seconds in the parking lot and went to "flop her upright" and it didn't "flop". My body went one way and the bike went another. Oops. I picked myself up off of the pavement, and shut down the bike and unlocked the forks, and proceeded to get it back on its wheels instead of its side. I looked around the parking lot very carefully to know if anyone saw my stupidity. The coast was clear and I rode on and vowed to not do that again.
