I don't see how those things will improve profitability.
It’s not obvious how those things will improve profitability, is it?
Putting more people in a vehicle means a lower price per passenger. I want to get from A to B without having to stop at D, E, and F. I used to HATE airport shared rides that did that, but I used them because they were so much cheaper than a private car straight to the airport. I expect a deep discount if you make me stop at D, E and F on the way to my destination.
