There was a similar issue with Cities Skylines. When they tried to put a realistic amount of parking lot space for modern US cities in, the simulation would have the cities quickly decay and collapse. It was just too much room and distance required to support the parking area. It cost too much and the travel times were too high due to the expanded city distances.

They took out the real parking and made cute little lots instead so the game would stay viable.

Of course, our real city leadership most ignores this warning and says “let’s add more parking and lanes for those ever larger vehicles!” My city’s downtown is about 30% dedicated to off street parking and there’s moves afoot to increase the number of they can knock down a few more buildings to make space.

Oh, and we declared a parking garage an official city historical site. That one’s a little on the nose.
