Why is there an option to skip optimization?

Even if the focus of the Upper - Route Planning App is to give you the best-optimized experience for each route you create, there are instances where the user might want to change their plans during the trip. It might be because few of the stops are closed for business during the trip and there is a specific need for the user to reach a certain stop first.

So, once you have chosen to Start Route and complete the few stops with no optimization, you can go back and re-optimize the remaining route for the best results for remaining stops.
