Do we really need to spend every commute hour working? To me long commutes, although sometimes tiring, have been a time to catch up on reading, listening to podcasts or just zoning out and thinking about nothing and everything.
Of course, we don't want to waste 2 hours of our day commuting, but this is the case to advocate for better public transportation that could take us quicker and more comfortably rather than believing that self-driving cars are the solution.
Reading is productive work, as is zoning out! Driving a car in a gridlock...no so much.
Though I was also thinking that on days you're expected to be in on-site, if the job makes it possible, you can potentially improve your commute by coming in later/leaving earlier while still being available during regular business hours.
