I run out of gas
I tried to wait out the gas panic, telecommuting some days and driving my spouse's car on others.
Over the weekend we were on a trip to South Carolina, which generally has lower gas prices. We took my car because it's more expensive to fill up, so it would have bigger savings. Skipped one station on the way in, and then tried all of them on the way out.
Those gas stations came in 2 varities: out of gas, and only basic gasoline.
My car needs premium, so I'm pretty much out of luck. Experimentation a few years ago showed that it needs about 90.5 octane, so I was able to dilute the 93 in my tank with some 87 to give myself a little more range.
But the lesson to me is clear: next time, I need to panic with the rest of the masses.
