Or, so I was told...
I was hanging out at the firehouse this afternoon, watching a fellow firefighter wash his pickup. I noticed a RD sitting on his dash and asked him what brand it was. He walked over and started looking through the window and somebody said "What, you don't know what it is?" He answered "Cobra, I think... They don't work anyhow" His brother is a city cop and told him they did tests in the academy and they got speed readings before the detectors activated.
I was gonna argue with him and tell him that I can pick up Ka band over a mile away, but wasn't bored enough. hehe There are two city cops that are also volunteers at my firehouse, I may ask them to set up a speed trap for me to crash one day.
Oh, we had just come back from a gasoline spill (the gas tank fell out of a car, pretty funny) and I noticed a RD sitting on his dash, too. I got close and noticed "Cobra" on it. A total stealth install, too!
