My commute is 40 miles RT. If it were 60 instead, I would find it hard to get all my work hours in and deal with home life too. But I'm totally car free. If I were instead considering doing this just a couple days a week, I could fit it into my schedule. You just have to look at the time involved and decide what might work for you personally. Since you drive and don't HAVE to bicycle commute every day it seems like you could do it when you have time, and not when you don't.
