Three things prevent me from losing the CR-V for a Segway:
1) Living on the second floor of an elevatorless building makes for a hard parking dilemma.
2) 1618 is out of the range of all but the most-charged Segways.
3) I don't own the CR-V officially.
That said, after I get settled whereever I wind up, I'd certainly consider it as an option (probably in combination with some form of mass transit). Insurance (and maintenance, and gas for that matter) is a beast.
