Finding the easiest way to solve a problem given constraints is a poor exemplar of propaganda. I’m sure it is and was possible to build perfectly lovely car centric cities in various Sim City games. If your problem is congestion you need to increase capacity. This requires either bigger tubes (freeways instead of single lane roads) or fitting more stuff into the same tubes, greater pressure (a tram or some other form of rail). If you want to maintain a historic city you can’t do a total rebuild so you can’t build freeways. Thus rail is the only solution apart from congestion charges. Reality constrains possible solutions. If you model reality in a game the solutions won’t be too much different.
