This means that I couldn't read anything. Shaking of the bus also gives me time to time a mild headache. Now if the ride was smoother (like a train or a tram) and I still could sit and read then indeed I would agree with you.
Fortunately I don't have to commute very often so I can tolerate this to a degree but if I had to commute every day then it would add considerable extra strain into my life.
Normally the day should be divided into 3 equal parts: 1 sleep time, 2 work time, 3 personal time.
Commute time effectively steals from either personal time or from sleep time and this comes on top of getting ready for work that is also a major waste of time in the mornings.
