It would be very nice to have the ability to correct or change the road we are driving on. If at any point we deviate from a GPS route (exit the highway early or late, enter an HOV lane, get or stay on an express road), we need to have the ability to adjust our location on the map so the route can update.

How to achieve this:
I'm thinking we could select our vehicle on the map (currently, this pulls up our "current location"), then - select an option to "adjust route" (call it whatever you want), this would pull up another pop-up window that would provide us other streets in the immediate area (preferably in the same direction we're currently driving) that we could then choose and adjust our current route/position.

Another example of why this would be useful:
Sometimes when we start the app, GPS shows us on a nearby road or facing the opposite direction. This can affect routes and anticipated ETA's, sometimes drastically. If we could select the correct street we are on, or the correct direction we're facing, it would be a great help/tool.
