Reading over different posts I see a lot of ppl say stuff like "so I was going 69 in a 65 and and my RD went off and saved me"..
While that is cool and all did your RD really save you? You probably werent even going fast enough to be pulled in the first place..And you should save the hundreds of dollars for something other than a RD.
I say, if you go more than 10 over on the highway than you really need one..If you dont then its prolly just a fun toy to have with you.
Just wondering how many of you actually RELY on it to keep you from getting a ticket and how many of you just think its a cool gadget to have.
