- Why would you calculate anything per hour of drive time? The mile is a standard unit of distance that fuel economy is based on... and doesn't rely on some arbitrary assumed average speed (how the hell do you get 30mph average anyway?). You should use $/mile, which you could then easily scale based on how far away you are from work and such. (Based on your 30mpg and $4/gal, you get $0.133/mile)
I calculated the cost per hour in order to compare to Zipcar.
Ideally, one could use the following:
- public transit + bicycle to commute to work
- Zipcar / Uber on weekends for heavy shopping and getting out of town for the day
- car rentals for long trips
Granted, if you are a country bumpkin then this wouldn't work. But if you have halfway-decent bus/train service (less than 1.5 hours from home to work) then it makes so much more sense. While someone else drives the train/bus then you just mess around on your iPhone.
If you live in a big city and have a car then you are a filthy barbarian like Rob Ford.
