My brother used to be a state trooper, and in the state where he used to work if you where caught with a radar / laser detector, you would be hit with a very large fine and the loss of the detector. If you where caught with a radar / laser jammer, you would be hit with an extremely large fine, a night or two in jail and loss of the vehicle you where using the jammer in!:gaah:
Thankfully TX has only instituted laws like this for big rigs.
Car&Driver (and NHTSA for that matter) has done multiple studies and found that there is no rhyme nor reason to setting speed limits. They have found that with no posted speed limit, the vast majority of drivers will travel at a safe speed for that road. Both have also found roads where the speed limit changes simply because the road enters another jurisdiction. Nothing else changed; the population density, business district, etc....
nothing changed except the road entering another law enforcement district. And guess what, most of the time there is a police car just past the speed limit sign. There is a perfect example of that in San Antonio on the NW side. I can't remember the road now, been too long, maybe you San Antonio people can help me out?
That is why I know speed limits have nothing to do with safety and everything to do with revenue generation.
Another little tidbit while I am ranting about revenue generation with traffic laws, when a camera is installed at an intersection, the duration of the yellow light is
always shortened. Again, Car&Driver as well as many other car magazines have timed a yellow light at an intersection before a camera was installed and then after and the duration was always shortened, sometimes up to a full second or two. Which while it doesn't sound like much, makes a huge difference when caught in that "Do I stop or do I go through?" In fact, using NHTSA data, it is proven that accidents actually
increase at camera monitored stop lights. Sound like safety to you?
