Better seatbelts would be an improvement, but you can buy that if you want. The standard speed limit on Idaho freeways is 75 MPH. Perfectly fine. Speeders are easy to catch. A good RADAR and LIDAR gun can precisely identify the car and calibrated speed with 1/10 MPH. If you want to speed, feel free. The officers will decide whether your behavior is bad enough to write an iron clad ticket. The local cops generally insist on an 8 to 10 MPH over posted so there is no room to argue in court.
We're happy to even have fire trucks, much less have GPS on them.
I just hear more and more good things about Idaho, The dirt bike riding opportunies are said to be exquisite, and highly technical. But still, I've got all this salt water in my veins...
