If the most significant difference between a bus/train and a self driving car is the ability to deliver you to your doorstep, I will take the bus/train. Think of the benefits - you don't need to buy and maintain the self-driving car, and hence all the other things like insurance, parking etc. The city doesn't have to build more and more roads. Get a bit of exercise walking to your door. Really, I think these self-driving cars are just the auto manufacturers trying to extend the lifetime of their products.
