I’m working up to commuting only by bike, but I still take a car now and then. My goal is to sell the car after I can demonstrate that I don’t use it anymore. Of course, I wiped out on my last commute by hitting some snow. Now I’m in pain for a while as my body heals. Hasn’t taken away any of the motivation to ride though. Even a wipe out on a bike is better than riding in my car to work, and I’ll continue to ride year round, regardless of the weather (if I can).
