This is biased towards hyper-aggressive vehicular cycling. I think it's really bad advice for new commuters.

I would focus on finding the safest route...look for bike lanes/bike infrastructure and don't feel afraid to bike slowly and cautiously on the sidewalk when things get hairy (as will inevitably happen when you first bike for transport).
