I had a car-related one.
One day, my car's gearbox broke, and I couldn't get reverse gear. I was very proud of myself for managing to get out of the parking space I was in despite this, then phoned Dave-at-the-garage who said to bring it straight down and he'd check it out for me. So, I drove back home, intending to drive pas t the house, and on down to the garage. And then, on autopilot, turned in through the gateway at home and parked in my usual spot between the wall and my parents car.
At which point I remembered the part about having no reverse gear. And that the gateway is pretty narrow, so not one which the tow-truck fits through easily.
