Old people!

Masket's thread made me think of this:
I glare at old people. Not just any old people, but driving old people. I hate them. Fucking driving old people. There is nothing quite like watching an old person pull into a parking spot that is straight in front of them, mind you, and observing that they are so crooked that they are taking up three spots. What the f*ck?!
This brings me to another point:
If you park, and notice that you are on a line, you should back up and try again. Seriously, this does not make you less of a person. I am an excellent parker (including parallel), and I will squeeze my shitty Camry in between two massive pickup trucks that are on both of my lines because I know that if their dumb ass hits me, it's their problem. You can pay for my new quarter panel.
I've also considered leaving notes for people discussing (with much foul language) their parking abilities. I really hate bad parking.
Anyhow, what do ya'll think should be done about bad drivers? If someone is a hazard on the road, what should be done about them?
