With self driving cars, the commute could be part of the work day, rather than added on top of the work day.

I just got to thinking, when the self driving car arrives, it can be a big time saver. People can work in their cars as they are being driven to work, by the car. The commute can become part of the work day. If society is smart (tho I'm not holding my breath) folks would need to spend less time at the office since they can get much of their work done on the way to and from the office. Time at the office could still be used for interactive, face to face things such as meetings. Some of the rest of the cubicle time could be done in the car. This could free up more time for family life and so forth. Today, people have both the long work day and the long commute on top of that. If cars must still prevail, the cars of the future must be run on green energy, however.
