There is some wisdom here, but for me driving to and from work, it is a minimum of 25 miles, lasting about 40 minutes per day. That is 200 minutes per standard a week, not including any other driving. Over 50 weeks, that is 10,000 hours, or the equivalent 7 24-hour days of driving, not including other driving around town, road trips, etc. There is something to be said for good seats, ride quality, safety, and a few bells and whistles to make that time more enjoyable if not less unhealthy. Not at the expense of financial security, and certainly not at the expense of having to work years longer.
