Personally, I would heed the coach's advice. Otherwise, you won't go anywhere in your racing ambitions. I used to commute by bike because I was free of car ownership, but there were occasions when I chose to commute by bus. I found it quite relaxing, even if it seemed a little longer and convoluted. But then, where I chose to live at the time was very well served by bus services.

I also wonder why you step-daughter can't get out there and work for her own transport. Why isn't she riding a bicycle at least occasionally, freeing up your motor vehicle for your use?
