AC has a few maps, like glencoe, wangan expressways, lake louise etc. that's if you just want to drive around without realistic traffic.
FH4 would be great otherwise but the cars seem to get caught in unnecessary tankslappers and there's no fine point of balance, but the surroundings are pretty nice and you can pretty much drive anywhere in the game.
ofc there's also city car driving simulators in steam that have a variety of mods if you want traffic situations too, and Euro truck simulators have pretty nice roads except everything is squished down into 1:10 scale of real stuff.
