I actually just got the radar detector and have been fine since. I didn't want one in fear that I would have 'too much faith in it', but 5 tickets into the year I decided I can't be any worse and most of my tickets are trivial 10-15MPH over so it should help. Luckily in Missouri, you can simply pay a traffic lawyer to get your ticket changed to a non-moving viloation for an extra 150 bucks or so. God bless America!
But I will stick with the point that for any guy in his 20's needs to factor in at least a few speeding tickets a year and arguably the increase of cost in going to nicer restaurants with better looking women (but that may be getting too nitty gritty).
