Police target ages 16-25 because that is the age that causes the most accidents. I heard a cop say at on point in time that he will pull over a 20 yr old in a pickup truck going 10 mph over the speed limit before I will pull over a 40 yr old doing 20 over. Fair and just? No True? Definitly.
I have had 8 speeding tickets and am on driving probation. Take it from me if you have the chance (in a first ticket scenario you normally do, at least in the states) take driving school and get it off your record.
