Why doesn't Uber/Lyft support actual carpooling so that if I know I need to go somewhere I can offers other people a ride to/from nearby locations. Given the traffic in large cities and the number of single cars going the same direction at rush hour it would make a lot of sense. Adding the option for a longer wait like this would make it easier to manage for the commuting driver. I guess the issue is it'll annoy the more professional drivers but for users it would be good.
