The bar is not (only) about Facebook, it was just "misused" to also show any FB friends heading up to the same destination (if your client is connected to FB, you can see the difference on my screenshots if it is not). The bar's functionality is already there, in the client, just that it is used only prior to the initial route confirmation:
and not also after tapping the ETA bar (which would be a straightforward way to show it):
Possibly minor code changes are necessary to add it for the (or some) next

Then already the existing bar would be breaching the patent. Except that the patent would only cover showing the bar during the navigation, but not prior to it.
