I'm not on the Amazon Fresh/Instacart trend yet (and may not be -- I really enjoy grocery shopping and frequent different farmers' markets, so it's not a problem I need to have solved for me). But as for Uber/Lyft, the reason they're vastly more valuable than whatever local taxi website/app is convenience and lack of friction. When you get an Uber, you don't have to worry about payment or directions; it's all handled for you. When you get to a different city, you don't have to google the local taxi companies and pick one; you just open Lyft and get a ride.
