CC, sorry to hear about the accident, but best wishes for your effort to remain car free.

Yes, I agree that it's not always easy to be car free. However, the luckier you are and the more carfree technique you can develop, the less you'll need the steely eyes and iron determination. There are lots of obstacles that need to be figured out. I don't recall anyone raising the question of cold weather asthma here on LCF, so I guess you'll have to be the expert.
