Speaking as someone who walks betwen 4 and 5 miles a day, the higher calorie count is nice. But I suspect totally meaningless. A basic pedometer would be a better choice if you are worried about activity or weight loss.

I do try to calcuate the costs in my head. I use a .25 cents/M approach for driving. (15 MPG, about $3 gas, comes to about 20 cents but easier to do in quarters). 4 mile trip is about a dollar in gas, or about a 1/3 of a gallon.

1/3 of a gallon of gas has about 10,000 calories of energy. Cost of that -- again, let's say a dollar.

Same ernergy to walk -- about four tablespoons of olive oil.

My takeaway: human body is very efficient when you dont drag 3000 pounds of car along with you. Gasoline is very cheap -- it is hard to find $1 for 500 calories.

The best choice is all of this is a scooter. The externalities of injury keep that option limited.
