Only tangentially on topic, but I imagine someone here knows the answer: is there currently an Airbnb for cars?

AirBnb lets you monetize your spare housing capacity for rent.

Congested cities are full of cars with spare capacity that isn't being monetized. I'm not the only one that's noticed this. Someone will eventually try to use smartphones + ridesharing to use this spare capacity.

Is anyone doing it at present?

Lyft, Sidecar, Ridejoy, Tickengo, Reward Ride, Avego, Carpooling.com, RelayRides, and a bunch of other ones.

I know of two, but I can't think of either name right now. One of them presented at TC Disrupt in NYC back in, I think, 2010.

RelayRides comes to mind.
