Nah, driving is also stressful and traffic is not fun.

I’ve seen recently a fair amount of car enthusiasts start buying into the walkable cities/public transit mantra, because a car enthusiast does not find city/suburban stop and go traffic to be the thing they’re enthusiastic about.

Right but that didn't change in last 20 years. Cities that suck driving (and walking) in now sucked as much and more 20 years ago. It's not that that changed how much people want to have driving license.

The amount of delay has increased over the last 20 years with a blip when everybody was locked down. Lane miles have not kept up with population growth or increasing sprawl, and investment in alternatives to traffic is quite poor.
