In my experience it's mostly due to convenience. When public transportation is available and more convenient, it's heavily used. It needs to be available everywhere and all/most of the time. Car pooling is similar, coordinating with other people, leaving home/work at the same time everyday is difficult, not convenient. If Lyft is widely used, it can solve this problem. No need to have advanced plans. In fact, in Washington DC, I can see people offering these rides for free to a second person in the car and use the HOV lanes. This is already done from fixed locations without the help of an app. Lyft would make it so much easier.
