My guess is that a near term local maxima is the combination of Lyft/Uber and a bus - or Uber Pool on steroids. It's very rare that I need to leave now, usually if I leave sometime in the next 30 minutes that is sufficient. Furthermore I don't mind walking a minute or two to get to the car/bus, or from the car/bus to my final destination. Relaxing the constraints on time and distance will (my guess) vastly increase the number of people that want to go on a similar route as me. Therefore depending on how many people get matched up the system can intelligently assign the right type of vehicle (small car, SUV, small bus, big bus).
