People can’t travel 30 miles from their home to the office entirely using public transit. Walkable cities and light rail are Last-mile. Heck - throw in high-speed for the majority of the transit and you still have a huge first-mile problem, which is by far the hardest to solve.

The reasons modern cities are designed around cars is because cars are flexible. Add a street for a new row of houses and every single one of those points is connected to every end point in a single step. No new scheduling, routing, or transit lines required. Problem solved with a little asphalt.

It’s an easy solution, and backing out of it is very, very difficult because it must be replaced with a complicated, expensive solution that’s less-convenient for most users.

I’m not anti-transit at all, but people around here seem to believe that a city can be fixed with the power of wishes and fairy dust just because another city that covers 1/10th the area and was developed hundreds of years before auto-centric decelopment ago managed to do it.
