Earlier quoted context omitted.
I find that to be completely true-- the area around my office is completely void of Car2Go cars from around 4 PM later. I had to walk ~1/5 of a mile to get to the nearest one. Of course, I'm sure at 1 AM that you'd be able to find a parked car pretty close to you, provided you're not by a bunch of offices which have had the cars driven away to residential areas by people at their jobs.
I had to walk ~1/5 of a mile to get to the nearest one. Which is what, a 4 minute walk? That seems pretty minimal to me.
In what way is ~1250 feet considered a far distance to go for a rental car? Even in a populous metro area that seems about as short a walk as I would expect, are they generally closer?
