I'm curious about the context of the $13,000 price tag. Is this a slight upcharge? Or an order of magnitude? I'm what the Brits might call a "keen motorist", but as someone who considers speed enforcement a necessary evil, there's a world of difference between paying a bit more for much better tech, versus way more. If this costs 4x what a normal radar gun costs, one must ask "what is the problem we're solving", and…
The point of distributing this technology is to make every motorist feel that nowhere is "safe" for them to speed. It doesn't matter if there are no cops around, their beams can get you and fine you, and hopefully that keeps people at safe driving speeds.
Most of the drivers that drive at extreme speeds are usually very rich (they are always driving Mercs, Range Rovers, Audis and BMWs) and don't typically give a toss about the fine or the points.
Also there are many people (usually immigrants) who drive without a valid license and insurance.
