The other cool thing vs zipcar is they let you take the cars one way, so I do downtown Oakland to/from airport for $12, which is cheaper than anything but BART, and far faster. And easier with luggage. And since I seem to often need to be on a flight when BART is still closed, I either drive/park or drive now basically all the time.
The problem is the car isn't really very big, is heavy due to batteries and compromises, and if I drive it at all aggressively like my personal car, I can make it go sideways.
80 miles range and slow charging means it is basically SF-Oakland-Berkeley only, or maybe SF to Palo Alto and back. I burned 50% just driving downtown Oakland to ups depot in downtown SF to SFO, with 15 minutes of idling at UPS, somehow.
If someone did this with a better car, like a Tesla, I'd be all over it.
$12/trip still makes sense for one-ways, but $30/day was awesome. At $30/day it was almost worth it to go across the bridge in HOVland in the morning and keep it all day.
$900/month, better then lease + insurance + maintenance + gas + parking + bridge. By $500+ a month.
Bummer. Doesn't sound much like the Ultimate Driving Machine.
