Telecommuting is going to have a huge impact. Today's technology can easily create the tools needed to make the home office environment as rich or richer than the traditional "face-to-face office environment. I find it a bit weird that people are talking so much about rapid transit, more walkable cities, etc when these things will take decades and 10's of billions of dollars to have a significant impact on oil consumption. Telecommuting can be done today, it pays for itself immediately (less office space, mileage, traffic congestion, etc) and can reduce oil use more than any other approach.

Yeah, ask a single parent about what a lifestyle improvement that mandatory four-day week is.

Hey, its Utah! They don't have single parents in Utah.

The only thing I don't like about telecommuting is never leaving the office. And yet still the place is never straightened up.

For someone who has a straight 40-hour job, there's fairly little difference in daily routine between working 9-5 or 8-6 (only child care is affected, if applicable). The best work schedule I ever had was Friday-Monday 8-6. I was still leaving early in the morning, and getting home in the early evening, but I had a 3-day solid block off, and I only had to make the 20-some mile trip to work 4 times a week.

The only problem being that the people probably drive twice as much on the extra day off as they would have working. Just because they aren't working it doesn't mean they are sitting at home saving gas.
