Roundabouts and public transit improvements cost millions or billions and take years or decades to roll out. They’re great, and we should build them, but there’s a lot to be said for quicker, cheaper solutions in the mean time.
I’ve got theories, but I don’t really know what the best way is to fix that. We probably need to try a bunch of things, and I’m all for that.
But drivers running red lights kill people. I’m for for the ideal, elegant solutions, and also for the imperfect incremental ones. I really don’t think worse-is-better, if that’s what you’re advocating, is appropriate.
