That was a bit tongue in cheek, but my point is that we’re ignoring an obvious solution due to inertia. Here’s a short video by John Stossel interviewing the mayor of Carmel, Indiana, which converted to roundabouts, and here’s a longer CNBC video about them as well. That second video is interesting because it shows that roundabouts started here in the US, but fell out of favor when salespeople pitched signals as cities electrified.

Here’s a video that’s a bit more critical, and the main argument against roundabouts is they’re expensive and disruptive to put in. That’s true, but it doesn’t explain why new signal-based intersections are put in.

Politicians will take the lowest fiction solution to keep their positions. Switching to roundabouts is a large political risk, even if it’s backed by science. People hate change, and roundabouts are annoying to get used to.
