Taxi cab medallions are a very poor example to cite. I'm empathetic to the story of terrible customer service and share sentiments about the overall erosion of user experience with many tech-adjacent, so-called disruptive services, but the second anyone suggests we were better off with the taxi cab than Uber or Lyft, they lose all credibility in my eyes. I think the biggest benefit that many fail to mention is that you can actually get rides when and where you need to. For example, people have far fewer excuses to drunk drive from bars in my hometown now than they did 15 years ago. I've had my skin saved by several rides that would be impossible without ride-sharing services.
