Too bad that doesn't exist,

You've never been to most places then. Drive between El Paso and San Antonio - 600 miles and only a few towns in between - all those are not very populated (<15,000). Speed limit is 80 most of the way - mostly flat so radar detectors give really good advanced warnings. The same could be said for NM, AZ, KS,OK, and most other states west of the Mississippi river until you get to the west coast and even large chunks of those states as well.

Edit: I have a downvote on that post? Seems I have a douche-nozzle following me.
