I was under the impression that if a rider inserted a pickup point and a destination that exceeded a certain limit (30 miles?) that the app wouldn't accept it off the cuff. Then yesterday I had a pickup at Jordan Creek in the late afternoon, no surging. The destination was already set for the trip: Northwest campus town in Ames. almost 48 miles. The rider said it was her first day as an Uber user, and the app was fighting with her on the destination, but she eventually got it to work. I also had a wierd one last night where the pickup and destination address was exactly the same, and not where the rider was. He was very apologetic, called me right away, and explained the situation to me. Yesterday just seemed "odd" with pickups for some reason.
