If this nation really was serious about cutting back on fuel consumption, it would move to 4 day work weeks vs. the traditional 5 day.
This would amount to a 20% savings in fuel consumption for commuters as they would travel to and from work one less day each week.
This country could move much of it's business to a 4 - 10 hour days and achieve the same amount of work as we do with the 5 day - 8 hour work weeks.
