re: Has anyone gone "full Uber"?

I live in Arlington VA near Courthouse Metro and recently bought a car. Before doing this I did the math. My conclusion was that having my own car was indeed more expensive, but not hugely so.

Full Uber plus public transportation would be a very reasonable alternative and I know several people at work who do this. It takes extra time to get familiar with doing route planning for each trip though, in the end I decided to just get a car and not worry about that, I'm at a point in life where it just isn't worth the money saved. But between Uber, ZipCar (rent by the hour), public bike rental, public buses and the trains you really can get just about anywhere.

Not that long ago I went on an African safari in Tanzania. I didn't enter a car or truck until I got to my destination on the other side of the fricking planet. I walked out my front door to a subway two blocks away, rode that to an Amtrak station, then to the airport, etc.
