This only works if you live in areas with no traffic. I have had multiple commutes in different cities, and would take a train whenever possible because of how unpleasant the drive is during rush hour (not to mention driving took longer, in one case 2.5x as long!). I don’t even live in a city, I’m just forced to commute because that’s where the work is. I love cars and have been an enthusiast all my life, but there are many reasons why public transportation is so popular around the world. The US might be somewhat unique in the challenges it faces with public transit, but it is still a better, cleaner, cheaper, and more efficient solution for most of the miles Americans are driving in cities or other congested areas.
I’m not sure if you realize this if you are outside the US, but debt in the country is at or near all time highs. Over 70% of people live paycheck to paycheck (some of those don’t have expenses fully covered, even), and roughly 10% are below the poverty line. Unfortunately, as much as many of us would like to strike, we don’t have the resources. A weeks long strike would mean many people couldn’t feed themselves or their children, or even afford basic necessities. The other issue is that many of those involved in all the MAGA nonsense will call for violence against protestors, even do things like drive a car through a crowd of them.
