"prohibit legal vehicle access?"
When i used to haunt the NJ Pine Barrens, from the late 1960's thru the 70's and 80's and early to mid 90's, and then occasionally into the early 2000's and even a couple of times since, there was pretty much nobody at all driving on those roads except me in my VW and Subaru. No off road vehicles at all. Nobody. The vast woods were all mine. I could hike and camp for days on end without seeing a soul, sometimes an occasional Piney who was never unfriendly to me, except one man who i inadvertently camped practically in his back yard. I had walked down a trail thinking i was far away from everything but unbeknownst to me the trail came right up to his house (not nearly as bad as what I did once in Fahnestock State Park in NY, tho!) Now there are off road vehicles out here in the desert too, kicking up dust.
