It's really just a question of being allowed to know where the police are and what they are doing, since they are allowed to know where you are and what you are doing!
Was in VA a few years ago, and everyone was driving like they were on the way to a funeral.
Every single road, to include interestates and highways!
Ugh!
The ban is absurd on its face. The ban reveals that speed enforcement is not about speed or enforcement, but revenue.
For a motorist to not know where the police are using radar using a passive device is just weak. To use a jammer, which is not passive is reasonable to prohibit. But even then it is still thin.
They are worthless on city streets, and if you’re speeding on city streets you deserve a ticket. The experssways are just that express. The speed limits on them should be flexible depending on traffic and conditions.
