I'll give you some more advice that I hope you also find sage-y. Don't wimp out too quickly either. I'm not saying that driving today is wimping out too quickly, but don't set a habit of deciding to drive instead of ride just vaguely "sometimes", for the reason of "maybe I should".

I recommend you lay out some concrete goals; how many days per week/month do you want to be riding once you've grown past the initial hump? How long do you want to allow yourself to get to that point? Give yourself a weekly allowance of driving days that ramps down from here to there, and get somebody else to monitor your progress with you and help keep you accountable. If not your wife, I'm sure the nice folks here at BF would be glad to help!

Don't forget to include in your long term expectations some consideration of how you expect to deal with rain, snow, cold, Dr/Dentist appointments, etc, all the things that will definitely come up, and how you will decide whether they demand a special driving day.
