An app that’s like Uber or Lyft, but it only calls your friends who have cars and would be willing/able to give you a ride. It shows you how far they are (if they share location with the app) and how long it would take to get you to your destination. Based on the trip distance and current prices, it could also suggest how much you would owe if you wanted to cover their gas.

I have an inside joke with a friend who lives nearby that if she ever needs a ride she should download an app that’s like Uber but it only calls me. I think if I actually made it, she would actually put it in her rideshare folder and use it instead of forgetting to message me! So yeah if you made it and it was open source I might actually use it haha
