And then there are people who just speed for the sake of it. If the speed limit were 160, they would do 170.Not true...if he radars the guy in front of you then you get a warning before you get busted; that is 50% of the time so it is still worth it to get the warning from the detector verses not. But yes, otherwise I agree, if it is you by yourself speeding, the detector just lets you know you've been caught. Speeding tickets are another form of revenue collection. A guy doing 72 in a 60 is not the same as a guy doing 92 in a 60...I don't see how these cops live with themselves KNOWING the speed limits are intentionally set too low to increase revenue; meanwhile, THE PEOPLE WHO WROTE THE LAW AND THE COPS THAT ENFORCE IT will most likely never have to pay for speeding themselves...it is like living in Russia...any cop who claims to be a republican and busts people for stuff he does himself (such as speeding) is serving the totalitarians of the left. That's my opinion.
