Be glad you guys don't drive in Kansas- they just began a new program that outfitted regular commerical over the road trucks (Yellow Freight is the first participating) with 5 hidden cameras, hidden radar and an officer riding along. Then they radio ahead to a waiting patrolman to pull you over.
It's a tactic that almost no amount of radar detecting or jamming equipment will work against since they're spot monitoring you in the same lane at roughly matching speed with instant-on equipment.
The program is expected to net several hundred thousand dollars in fines over the NEXT SIX WEEKS! Here's the link:
