you are quite mistaken... the speeding tickets are not there to discourage illegal activity, they are there to make money. if it had anything to do with illegal activity at all, there would be no places where the speed limit decreases for a quarter mile for no reason whatsoever other than to catch people before they manage to slow down.
i would much rather they just sell us a license to speed for 100-200$ a year, and we have to take a special driving test to qualify. Either that or actually come up with a speed limit that makes sense. if i can safely drive 60 on a road or 100 on a highway, why should the limit be 30 for the road or 60 on the highway?
instead of coming up with some arbitrary speed at which it is safe for the average user to drive, and force people who suck at driving to drive at that speed(because going below the speed limit is dangerous), they should simply let people drive as quickly as they want to and then charge them out the wazoo when they do something stupid and injure someone. I would also love to see multi lane roads actually have variable limits based on your lane... so slow traffic is in one lane and fast traffic is in another.
