I think part of the problem here is that the public and government officials don't treat lack of charging infrastructure and broken chargers as an emergency. If a tree falls across a major road, you can bet there will be work crews showing up within hours to cut it up and move it aside to restore access, because a road with a tree across it doesn't function as a road anymore. We should treat lack of working charging…
Ideally EV owners would obtain a permit before blocking a highway. I would expect the violence to come from the state.

So, if you're right wing, you can shut down major cities for weeks with minimal consequences. I don't think EV owners protesting the sorry state of infrastructure would get the same treatment.
