I have a friend who drives seven hours from Los Angeles to San Francisco instead of flying, just so he doesn't have to take off his shoes at the TSA checkpoint.
I would rather fly than drive, but I can understand where my friend is coming from. TSA security is the worst part of flying for me – the lines, the liquids in a clear plastic bag, the laptop and kindles out, etc.
Fortunately, I pay for TSA Pre, so I don't have to take my shoes off, but my belt buckle always set off the metal detector. Last year I bought a belt with a plastic buckle on Amazon, which allows me to walk through the metal detector without taking it off. I fly a lot, so it's worth it. As an added bonus, there are no holes in the belt. I can make the belt exactly as tight as I want it, rather than deciding between using a slightly too lose, or to tight belt hole.
