An excellent question. The "traffic engineer" profession is deeply broken. https://www.nytimes.com/2023/01/06/us/widen-highways-traffic.html
Widening Highways Doesn’t Fix Traffic. So Why Do We Keep Doing It?

With billions of dollars available to improve transportation infrastructure, states have a chance to try new strategies for addressing congestion. But some habits are hard to break.

The New York Times

We now have overwhelming evidence from a million different directions that sprawly car culture *doesn't work*. Suburbs don't pay for themselves. More lanes don't decrease traffic. Stroads kill people & inhibit economic growth. Parking is economic deadweight.

We refuse to learn.

The whole car/sprawl complex has reached such size & momentum that it just thunders on despite all this evidence -- one of many ways the US punches itself in the face over & over again while bragging about exceptionalism.
@drvolts As I get older I dislike cars more every day. Once retired hopefully we’ll move to a city where they’re not needed🤞🤞🤞
@kbird @drvolts I did that in my early 30s (happily not work-constrained, though left a great job to make the move). Would recommend.
