I don't know people are still playing SimCity 2013 or not, but this is the only game I still play from time to time. Coming to the point, In my city, High Wealth Tourists (in purple color) are coming from Ferry Terminals and Airship Hanger which is normal but they're going out of the city through cars, I've Maglev Stations all over in my city and Double-Decker Bus Terminal with Bus Stops. I've placed Ferry Terminals, Airship Hanger, Commercial Buildings, Landmarks, and Casinos all of them close to each other, Medium and High Wealth tourists are commuting between them on their feet but ONLY High Wealth Tourists are using cars to go out of the city and this thing is creating all kind of problems in my city from Police to Fire Fighting to Omega Deliveries to Student Enrolling, I don't know from where they're getting cars and why they're not using the same medium they're coming into the city, you can see the attached screenshot, there's congestion only at the incoming lanes with High Wealth Tourists. Any Suggestion?
