> How cities are built and what transport infrastructure they're built around. Context is important. The population of cities has grown. For example, the Chicago metro area has 70% more people now than in 1950. Population growth has impacted car ownership and use. We shouldn't use today's context against the past. Things were different and that's worth considering. Urban areas are about 3% of the US physical space. The design of transportation for dense cities (and they are getting denser) is different from that of suburban or rural spaces. There is no one size fits all.
