Even if there was a great public transit option for my commute, I'd have to focus on aspects of work I could do because I get motion sickness pretty easily. Reading a laptop on a moving bus, train, or whatever is going to have me dizzy with a massive headache, then a lost hour recovering when I actually arrive. I do envy those who have the opportunity and capability to do this though.
The latter limitation will probably end soon with improved ML based background audio removal.
But, sure, let's go with that line - if you are salaried, and you have an hour each way commute, and your company okayed you working 6 hours a day (since your commute is 2), and they also paid you extra for mileage (to offset fuel and wear and tear), are you saying you'd object as strongly as the people objecting to those 2 hours ON TOP of 8 hours in the office, with no compensation for mileage?
Because that was my point; the general objection to commuting I've heard, and would raise myself, is that it is unpaid personal time. Not that it's just an unpleasant task that the company is compensating me fully for.
I read my email/catch-up on slack/read the newspaper during my 45 minute commute in the morning. While wfh I spend the time doing something pretty similar.
