Marty - I completely agree!!!
for my fulltime job I test software and help roll it out. Often times during rollouts we run into unique scenarios that we need to find a cost effective way to solve. Are they bullet proof? Nope they definitely are not, but they accopmlish the task effectively as long as you are aware of the nuiances. This "Default Route" idea falls into this category in my opinion
My more hopefully suggestion is to have a yard mode speed limit. I think that would be super useful, but I can't wait to get the hardware and test out the app!
