Ah, also about the taxi analogy, I think it's also a cultural thing. In my city, honest taxi drivers do ask for the client's preference of route, actually. We have a lot of taxi drivers asking for outrageous prices such as 3 or 4 times what the ride is worth (as opposed to the cab fare written on the car) and if you don't pay that much or unless you have very far to go, they just don't take you. Sorry, don't want to hijack the thread with my analogy, just thought I'd explain because that's something very specific to my country and city, so it may not have been understood.
