Sometimes in the inner cores, yes. But many North American cities are new. Built mostly post-war. For example, Calgary is a city of ~1.2 million now. In 1946 it was ~100,000. More than 90% of the city was built in the post-car era, and the main city planning stage (in the 50s and 60s during the population explosion) was of course, heavily car-centric. That's the legacy we're still living out, with similar stories in cities across North America.
