Yeah tom took the words right outta my mouth radar detectors are only good when the cops are actually using them so like you said on the highway they are useful but back roads and in town basically useless but the big tickets usually come from the back roads and not the highway so I won't be buying one ever again. Also the last one I had went off all the time in town for things in banks and other various business's which made me not ever use it. I just try to stay at pace with traffic or have a really good BS excuse why you were speeding already practiced because in town if you are speeding and a cop pulls you over if you say something like my mom was just in an accident and I am tryin to get to the hospital to see her 9 outta 10 times the cop will let ya go...
P.S. I wouldn't personally use that excuse cuz ya never know it may just come true Karma is a BAD THING... Maybe use my GF or Wife is having a baby right now and I'm trying to get there fast Its my first and I dont wanna miss it....
