I don't remember the exact specifics here, and the guy who wrote the article could have been a raving lunatic, for all I know, and maybe it was only like fifty miles, from one side of town to the other, but the point was, in traffic, you don't gain that much by driving like a maniac.
I can see removing speed limits for the long stretches, and some states have already done that - I think Montana, and maybe Wyoming, albeit my impression of Wyoming could be that it's more a matter of "why pay some guy to go out into the middle of nowhere to trap speeders?" so they just don't bother -
But the point was about defeating police radar. Why not just drive around?
I guess the point is, (A) it's so simple to breeze by a speed trap - just slow to the legal limit, and (B) the FCC has a thing about transmitters.
