Mississippi? I bet it's a flyover state with a tiny sliver of road that sees massive trucking volume.

It's gonna be California (but I'm guessing, not sure). Other states just defer to federal regulation.

That they don't put the state on blast sort of points to the big cost not being entirely real (where they either think they can induce regulatory change or the number of tests that is needed to sell the systems is quite a lot less than the number of tests that would be needed to allow 100% of the market to use their system).
