I think this oversimplifies life and realities.

You don't have to be "productive" all the time. As you put it, driving the car is not just a chore - things happen along the way. It can be a chore - I just contest the most unproductive label here.

By this token, sleeping is the most unproductive thing in the world. Except you recharge.

I enjoy driving for pleasure and often go for days long drives. Driving back and forth to work however is definitely a chore. It sounded fun at first, I get to do something I enjoy doing before work, how bad could it be?

Turns out, spend a couple hours on the road everyday and you'll quickly get sick of podcasts or ebooks. You can't stop to look up details or check out the code/math/design because you're driving. You can't really do anything else too because you really should be focusing your attention on the road.
