Those two hours can probably be struck off. Getting ready in the morning and evening, eating, and maybe an errand and that's gone.

Makes me wonder if these people are running from spouses they don't want.

Most definitely. Many people I know basically develop a relationship with the office because the relationship with the spouse is that difficult / messed up. As a person working from home, I have to sympathize with them : it takes a lot of work to keep a good relationship and working away from your spouse / significant other for n hours a day certainly makes sense. I suppose the problem is when n becomes greater than 8!

Most probably convert some of that commute time into leisure. Audiobooks, podcasts, radio possibly.

It's hard to enjoy a book when you're constantly scanning the highway for things crossing the road, or slowly inching up a lane of traffic. The concentration required for driving detracts from the audiobook experience. It's often better than driving in silence, but I'd hardly call it a replacement for leisure time. I reckon most people would rather be home.

I've found non-fiction audiobooks to be good when you can't devote full attention. I do find that fiction audiobooks are ok on interstates, though, for especially long drives.
