Try So-Cal Interstate or Roane County Tennessee maps. They both feature slightly thicker water densities to make sinking and driving through water-over-the-road sections more realistic.
Both maps have 120~163 miles of road in them, so you won't get bored fast. You'll need a half-decent computer with a fairly capable video card to enjoy anything-above-medium settings.

Turn off shadows and reflections if they're too slow (shadows help for cpu speed shortage, reflections will boost video FPS by 50~80%).

These should work for links. I have made both of these maps, please do not try this on your potatoes at home :) Use decent computer please.

AI should work 100% including all roads and bridges, and should keep lane on the freeways/hiways.

ALTITUDE and DESERT HIGHWAY and any one of the maps by Ouerbacker (look them up on the Beamng.drive forums), they're all good (they're not made by me)... they're all top notch, and Altitude in itself is one of the chart-toppers great for stunts and jumps, and inevitably falling down and losing lots of altitude.
Desert highway is good for cruising for just MILES, it's almost as big as my Roane County map, in fact, though it has been on the forums much longer.
Ouerbacker is a very accomplished modder, so do check out his maps also.
Avoid my Nevada Interstate map if you have an Nvidia card, or don't have So-Cal Interstate yet, as it's got some texture bugs and I haven't gotten around to updating it yet, OOPS.
