If you want stress free comfortable commuting, you're going to need to build an efficient way to move people.

Cars are not really an option when it comes to moving people en mass. It's just too low capacity.

Rome's metro system in particular is stymied by buried Roman artifacts and laws for archaeology. That's not really the worst thing, given that NYC subway construction cost are some of the highest in the world.

That said, I saw what Atlanta looks like. Aside from down Atlanta, a lot of Atlanta is literally just low rise, even downright suburban sometime. It's a smaller city than people thought, given that only half a million people lives within its border proper, but nonetheless traffic is somehow a nightmare.
