Some drivers can make it work. This has been stated before but some like myself who drive only select may wait up to 3-4 hours yes but that one trip equals 2 regular airport trips...without the extra mileage and time in traffic. Also, I can work on my business out there...or watch movies which is what I end up doing anyways haha.
It's likely the ones who wait out there don't feel the need to constantly drive because rideshare isn't their full time job.
