My solution for this is having an extremely crappy brake. It'll stop me just fine, but after I've applied it once, it sticks half-closed, just barely dragging on the rim (makes trackstanding a bit harder) and the brake lever goes loose and rattles over bumps. So every time I use the brake, I have to reach down and pull the brake arms back apart while I'm riding. I hate doing this, so I don't use the brake unless it's an emergency. And of course it was all on purpose...
