Lets do the actual math here.... I will use my commute since i know more of the details. Its close to the OP of your reply.... I travel 50 miles per day to work, round trip. This takes me about 65 minutes total on average. That is an average speed o 54 mph. If i were to bike that with an average speed of 16mph it would take me 3.125 hours. If i workout for an hour a day, which is a very considerable workout to do daily that puts me at 2.08 hours per day with driving verses 3.125 hours per day for biking. So by driving instead of biking i can still get plenty of exercise to stay healthy and save an hour per day to do other things i enjoy. Family time, cooking, programming, reading, etc. At this point i would say i will stick to driving. Don't get me wrong, i can't wait for driverless car technology... would love to have yet another hour back per day. the train and bus stuff doesn't work out well in rural pennsylvania. cars are pretty convenient here. the economics of cars works, and has for a long time, and in a capitalist based society, thats a large part of the equation. a lot depends on your measuring stick.
