Speaking of Slow Drivers...

Is there anything more annoying than when you're driving, and the person in front of you is creeping along like a visually-impaired, Asian grandmother, and you can't get around them, and then the green light up ahead changes to yellow, and they gun it to make it through the intersection, and you get stuck at the red light?! If you're physically capable of driving that fast, why weren't you doing it all along?!
