remember driverless taxis will be the end of CAB, if there are driverless ubers and driverless yellow cabs, why would anyone book a yellow cab? when the uber is still say 30% cheaper and neither have drivers, a lot of people say they would never use a driverless cab because they like the interaction they have with the human driver, but if both uber and a normal cab are driverless why book a normal yellow cab?

I just wonder what all these little old ladies that take a cab to woollies for $5 will do when all cabs are driverless, and old people are not good with their smart phones, I guess they will have to get their grandkids to show them how to do it, and who will help these old dears or people with a fold up wheel chair when all ubers and normal cabs are driverless?
