Where do you start when judging whether a city works?

• Its football results
• Its layout: distances, jobs, stations, roads
• Its flag and anthem

How do density and transport relate?

• They reinforce each other both ways
• They never affect each other
• Transit always destroys density

Roads, rail lines, and zoning are easy to undo at any time.

A city approves a rail line through new suburbs. Why is this decision weighty?

• Paint colour is permanent
• It shapes travel patterns for decades
• Trains never carry anyone

City A sprawls with weak buses; city B is compact with strong trains. How do workers travel?

• Both travel identically everywhere
• A bans cars while B bans trains
• A forces car use while B keeps car trips low

A fast-growing district gets homes but no new buses or water lines. What follows?

• Shorter trips for everyone
• Cleaner air automatically
• Crowding, dirty air, and strained services

Two cities have equal wealth, but one is crossed without a car and the other is not. What best explains it?

• Luck with the weather each year
• The number of flags flown
• Decades-old density, transit, and zoning choices

A mayor claims a traffic jam proves the city needs wider roads only. What layout question is missing?

• The mayor's favourite colour
• Whether homes, jobs, and transit line up along routes
• How loud car horns can get
