Has anyone ever actually used the travel time estimates in their app?
I've taken hundreds of rides, and I don't think I've even once looked.
I find it to be a completely pointless part of the whole product - I already know roughly how far away something is, and how bad traffic may be. When I call an Uber, I simply look at the surrounding map and see where the cars are to get a decent estimate. The one they give is usually off by quite a bit, depending on who accepts the hail.
I've chatted w/ some Uber engineers about this and the story I was told is that originally they were using Google Maps estimates. But the data is really important to capacity planning and giving travel time estimates within their app. And it was often very wrong. They even had a number -- something like "if you multiply google maps estimates by 1.5 they will actually be more accurate". So building a better version of this in-house, based on the millions of miles previously driven, was a very important and challenging problem.
