   No, and nothing like it. with self driving cars the individual car can   
   leave the collection of cars at any intersection if that makes sense.

   That isnt clear compared with driving the car yourself.

   No, it's because the self driving car can leave the collection   
   of cars at any intersection where that makes sense. That isnt   
   true of any train.

   True, but that is a relatively small factor in the   
   advantages of self driving cars over trains.
