Eh. Driving time isn't completely lost, but it is pretty low capacity if you want to study or be entertained. I used my metro commute for 3 years to learn programming languages, take college courses, read stacks of books, nap, learn to cook with cooking shows, and solve technical problems for work. I used my car commute for 3 years to...listen to some light entertainment and music. I managed to get a speeding ticket while listening to a podcast because I wasn't focused enough on driving.
