Looking on Google maps, 395 north of Bootleg is pretty much all a 2-lane undivided highway for as far as I tracked it. As such, what sort of defense do you think you can mount? There does not appear to be a median until Eastside Ln. (and that would have been a crappy and unsafe place to run radar!), and if that was where the stop was made, there'd be no reason to put down that the offense was north of Bootleg which is miles to the south.
Don't even see a median there. It's just a chicken lane which doesn't create a divided highway.
