My wife and I are ok with that level of outlay, and, most importantly, we are both psyched about the prospect. We will hang onto her Prius + my Zipcar membership for long trips, and only time will tell how much we rely on them as a crutch. I do know that when I didn't have a car of my own in 2008-2009 I used Zipcar for all of 22 hours in total over a 15 month period.
Or you could get a 25K Limited RAV4 and save a ****-ton and have the same vehicle. You could even spend the leftover money on a rickshaw when the family wont fit on the electric bike. This way, you won't be eating my tax dollars for feel-good 'eco-friendlyness'.
