V1 & it is great. But they are *not* cloaks of invisibility. Laser is detectable at a distance. These things are hand held & if it is flicked on while still being aimed, you have a chance. Ever shoot a hand gun at even a large target a couple of hundred feet away ... not so easy. And there is beam spread with Laser to make it a little easier to aim. Heisenberg had something to say about that.
Never speed when you are the only thing on the road ... DUH! A cop with even a 30 y/o radar gun will catch you.
Never be the head or the tail of a string of cars.
Never speed with a group especially if your car is red and/or you are under 30.
Never speed with cruise control.
Never use a jammer if you are the only thing on the road ... DUH!! Does this need explanation? If a number doesn't show up on the gun and you are the only car on the road ... what is the conclusion??? Hmmmmm ...
I often take really long driving trips ... 1000 miles or so ... and have for years. Speeding is a kind of a PITA actually. Some locales have so much radar I think you could heat a cup of coffee with what is floating around.
If you have a need for speed join
NASA. THAT is fun albeit a little rough on brake pads & tires, but if you can't pay don't play.
