A good transportation example exists right there in Detroit with the privately owned Detroit Bus Company.
They've ditched the old standard model of running regular routes whether anyone is riding or not. Instead you can find the nearest bus with a phone app and even call to have them pick you up at the nearest corner to where you are and drop you off near where you're going. They've also started chartering routes to neighborhoods where people want regular service. They give free rides to kids in after school programs and drop little old ladies right at their front door.
I also thought this was very cool. When someone broke in and trashed an ancient bar in Detroit, the Detroit Bus Company showed up with customers to help them get back on their feet.
