You remind me of a recent experience. I bought a second car, used. Turns out the battery was right at the end of its life, so if you drove the car every day, it was ok, but would be dead if it sat for two days. Realizing this, I was going to take it to get a new battery, and we have a nifty cigarette-lighter-to-cigarette-lighter charging cable, which is slower than using jumper cables, but also means you don't have to worry about electrocuting yourself or battery gas explosions.

As I was setting this up, I crushed one of the connectors in the car door. Whoops. But I have jumper cables too. But they wouldn't reach from the dead car to anywhere I could get the live car because of where other cars were parked. But I should be able to roll the dead car out of the parking space. Except it's an automatic transmission, so you can't just put it in neutral. Except (I found on the Internet) you can flip a little panel up and release the electronic shift lock. But that didn't do anything, maybe because the battery was dead? Oi oi oi. Eventually our neighbor moved his car.
