Seriously, what does it mean to route to a destination? On just about any device, you can route to a set of destinations. Obviously, you can route people by a destination that the user didn't specify. Obviously this could be a retailer or other business, if you had any reason to do so. Obviously if they pay you to do so, that would be a reason.
Where is the "invention" here? It uses all the existing APIs. It uses standard business practice (i.e. you do something if someone pays you to do it).
Seriously I am struggling here. Does this mean you can patent "route avoids streets that have restaurants that serve meat" to accommodate strict Hindus? "route avoids paths that would make the driver pass a church" to accommodate flaming atheists?
I can play this game all day. You can route trips for all sorts of random reasons other than quickest path, shortest path, avoids tolls, avoids highways, is acceptable for walking, is acceptable for bicycles. Heck, maybe if no patents exist for these, they can be patented "first" now.
All of this is obvious, but worse it is obviously not an invention. Just an idea and a bit of api work and common (sadly) business practice.
