There's a stretch of eastbound I-80 where CHP hangs out, and these hiding places result in zero chance to eyeball the cruisers lying in wait. With this cover and I/O, you're toast. Also, even with Redline, the amount of surrounding tall vegetation means very little range, due to radar absorption in the foliage.
There are about 20 of these little sneaky on-ramps, starting from just a few miles east of Auburn, ending near Donner summit.
In the video, there is a truck towing a large camper trailer about to enter the freeway. You can only make him out in the last seconds before he joins the freeway. So you can imagine a smaller, darker CHP cruiser parked just at the edge of the trees. (Maybe I will try to snag one on video on my next run)
