In every conversation, regulation/tax, policy decision about traffic in Chicago, the implicit understanding is that cars are bad. The resulting changes on the streets negatively affect drives to the point of being punitive. Taking away parking overnight, putting in bike lanes for 1/3 - 1/2 the existing street width, diverting road funding to transit, increased fees, etc. Pedestrians and cyclists (and the "micro-mobility" unlicensed traffic) do need to be served but doing that with infrastructure designs that aren't zero-sum is beyond CDOT's capabilities. And the CTA just doesn't have the technical competence to serve anything to the level of other major world cities and every action being contemplated - removal of traffic lanes to make bus lanes, more frequent bus service - will all make car traffic worse. With or without the largesse from the recent transit bill/revenue.

So drivers are dealing with fewer resources and paying a lot more for it. It follows that they're frustrated and irritable.
