Do car-sharing schemes work in the States?

Here in GA, the HoV lane works alright, as long as you are going strait through ATL. There are precious few exit ramps from that lane, and it is on the far left, making getting off the interstate difficult during high traffic times. Proper planning would have greatly improved the system, but it is GA, right? Barring that, sometimes the HoV lane has as many cars in it as the rest of the lanes, and it is also the lane accident cars pull into, so if there is an accident, that lane is screwed, and good luck getting over because those in the fast lane hate you for having passed them two miles back.
