In the Paris area, if you commute during rush hour, you'll probably been stuck between 100 people per square meter. At best, you can listen to some podcasts or audiobooks.

When I still had to work from the office, I was fortunate enough to be able to move my hours earlier so I could avoid morning rush hour and could, indeed, read in the morning. Afternoons I couldn't, more often than not.

It was just wasted time. I can also read on my couch before I start working from home. I've read many more books since I was able to WFH on most days.
