I see. And where would all these vehicles wait? At my local station, there just isn't the space for a hundred cars to wait every time a train arrives.

But you will still have to watch the road as you will still be ultimately responsible.
If that many people are using them to shuttle back and forth from the train station, I'm sure there'd be some kind of line-based system. The beauty of self-driving vehicles is instead of having it take you to the train station, it might be more feasible and comfortable for it to take you all the way to your destination.
