I used to speed a lot too....but now I drive like an old women most of the time....I'm not sure why I can't find a good middle ground. :dunno:

Anyway as far as your question goes you have only two options:
1.) Pay attention and don't speed
or
2.) Stop driving.

It really is that simple... if your not willing to make a conscious effort to monitor your speeding than you shouldn't be behind the wheel.
