There is road work everywhere. Streets are not that smooth. Apartments, people's walking remind me European cities. So that, owning a car is not a must. For the longer distance just take the bus and subway. And of course bike renting will allow you to commute about 30 minutes until next bike station. Many bike roads, if not, bikers are still riding on the streets. And it is all safe. A dead giveaway for being selected among green cities all the time. Historical basilicas are harmonized with modern buildings in downtown.
