I use Waze on my phone for my car nav. When I am stopped, it will often pop up a small advert for something near by (usually offering some sort of deal) with a single button that says something like "Go there". Tapping that button will reroute me. If this was built into the car nav of an autonomous vehicle, I don't see why it would need to be more complicated than what we already have in other apps today.
