If a ton of people take the 10x4 schedule, then there will just be a new rush hour. And the problem is working 10 hours a day, not working 4 days a week. This isn’t the 19th century. The idea that we even need to work 40 hours a week is playing into the hands of the capitalist oligarchs. They want you to be happy dong 10x4 and not, for example, 8x4 or 6x5. They think the more you work, the more productive you are when that’s utter bullshit and it just wears people out.
