I'd like to know more about how they manage grouping and pick-up to make this suitable for commuting and rush hours. Say there are 100 people in a neighborhood who commute to the city center each day around the same time. Does this mean there have to be 100 individual cars in operation, just for that neighborhood? Or does the service some smartness so that one car can collect multiple people? We had a similar service in my city, which was specifically optimized for group pickups. However it was structured in a way that would have made it completely unsuitable for commuting - I suspect intentionally, because they realised they didn't have the resources to serve rush-hours.
