That might be what you wish they are learning, but I assure you that's not the case. There may be more of those Highway blocking protests that you're thinking about, but you're simply hearing about them spread across many, many locations. They are not occurring frequently enough in one location to warrant a change to the way people commute. I have never even heard of anybody linking those two points together before.

If they're blocking a highway, it's not like you can just see the protest up ahead and turn off instead instead of choosing to be stuck. Often they are held in the middle of long stretches where they will trap as man cars as they are able on both sides.

And the lesson most people learned from COVID was that there was absolutely no reason why we couldn't work from home. Although I could potentially see a link between working from home and, when the time comes to replace the infrastructure, replacing it with something more environmentally sane... but they'd have to convince big business owners to not force people to come into work for no reason, and good luck with that.

It seems like there's a lot of wishful thinking to get from "those protesters are blocking this street" to "man, we should completely redo the entire infrastructure of North America because of these protests."
