From my personal perspective - taking a bus to work would take at least an hour each way, usually more depending on the traffic. Add standing at unheated bus stops in winter = no thank you. By car I get to work in 15-20 minutes. At the temperature I like, listening to music I like.
That easily saves me a good few hours each week for other activities - learning, relaxing, family time.
I could cycle, like I did while I was at uni - but that leaves a problem of getting sweaty, can't really cycle in a shirt, and cycling in winter is miserable.
Am I an "avarage joe" going to work from 9-5, or am I being wasteful? You tell me. I know what I'm going to continue doing :-)
