1) A U.S. map of 3 U.S.-style cities (of course, scaled down a bit in numbers of streets): one large modern one with a center city street grid section with high-rise buildings and some industries and a pro sports complex, surrounded by 3 suburban residential areas with housing groups and shopping centers and one industrial area with freight railroads. This would be 75 miles south of an older style U.S. city with brick buildings and one residential area of older style with north-south/east-west grid of streets. A typical U.S. Interstate system divided, controlled access freeway would connect the two. So about 75 miles of Interstate highway. 35 miles to the west of the northern city would be a small city with an old-time Main Street with 100-year old buildings and a surrounding residential commercial area. Connecting these two northern cities would be a 35-mile, 4-lane highway with occasional signal-controlled and non-signal intersections. Amongst these cities would be farmland with alternate routes of 2-way traffic highways (one lane in each direction) leading from city to city, with a couple very small towns along the way. Then paved county roads, dirt roads and gravel roads amongst the farmland. You could take the U.S. state of Iowa as an example, but maybe add a small mountain range (3,000 feet high) in the middle of the open country between the northern cities and the southern one. The Interstate highway would make its way realistically through the mountains, where the smaller highways would wind their way up and down the slopes of the mountains and use some tunnels.
2) U.S. standard Highway signs and traffic signs. Very long to explain, but in your current city, for American use, there is an insufficient number of speed limit signs, for example. The signs and road design, in general, are rather foreign to an American. (not saying they are bad, just not American)
3) Improve the penalty assessment system. I made a legal, normal left turn at a large intersection on the current map (I don't remember precisely where) and was penalized for driving on the wrong side of the road. Ridiculous. I suppose for a moment you could say I was on the wrong side of the road, but only during the curved path of the left turn to the cross street. Also, penalties for speeding when it is not apparent what the speed limit is on that road or street. Too many penalties for not using a turn signal. Seriously, your road layout is so complex and duplicitous that I find myself flipping the turn signal left and right continuously! I got penalized for stopping at a crosswalk for pedestrians. It said I wasn't stopped at the edge of a driveway. You can't turn around at a dead-end road barrier without being penalized, and you're penalized for driving down a road to a closed road barrier. And so I can't complete very many assignments because of minor technical deviations that are rung up as penalties, ending the assignment after just 1 or 2 of them.
4) U.S.-style automobiles (a Toyota sedan, a Chrysler minivan, a classic '57 Chevy Bel Air, an Isuzu N-series commercial truck, and a Ford F-150 pickup truck) with speedometers reading miles per hour!! Either the speed limit signs and speedometers need to all indicated MPH or all km/h. But, as is, I think they are MPH speed limit signs and km/h speedometers. In VR goggles, I can't see that digital MPH indicator that appears on my flat monitor. VR goggles are excellent in this game, by the way!!
5) Far fewer police cars in the game. Now given recent events, you might think Americans don't want any police. Not true, of course. But as is in this game, there are almost as many police cars on the road as private cars. Which is not very realistic for anywhere, I would guess. AI cars in this game seem to like to suddenly stop under road bridges, by the way...why?
