I know Waze would take just a little bit longer to update the route and I may have missed Tom Slick Dr because of that delay Waze has. Is there something in the programming that could be done to make Waze quicker at getting new directions when we veer off course? Or is there nothing that can be done because it's all based on how quickly GPS updates?
I don't know how this works, but I have a theory. Based on the GPS data, the maps app more or less knows where the vehicle is and how fast it's moving. But the iPhone also has a built-in compass and accelerometer. When you turn off route onto a side street, the accelerometer can detect the vehicle slowing down for the turn, and the compass detects the change in the vehicle orientation. Then the maps app thinks "hey, the guy is making a turn here, and based on the speed/location data I have we're most likely at intersection X now". It should be technically possible for the Waze app to do something like this.
