Altho' I believe it's less a worry about drinking and driving than it is the driving distance and the weekend time that creates this noise issue. Close in CG's allow noisy weekenders to reach the campground just for the weekend. Most won't drive all day to make noise. SO, more distant CG's won't get the weekenders ...
