Isn't Uber pool accomplishing this? The Uber pool model seems to be the most realistic gap filler between mass transit and an individual automobile. Rather than mass transit buying vehicles specifically to fill this gap, using the spare vehicular capacity of the car driving public seems like an efficiency. For example, my wife and I, in Las Vegas, now have only one car because Uber fills those rare moments where a second car is absolutely necessary. And Uber pool is even more cost effective, while also being a higher utilization of the car the Uber driver is driving.
