Research direction
Start by reading the legacy request in issue #764, the algorithm investigation in issue #3116, and the route-comparison conclusions in pull request #3301. Trace how selected alternative routes are handled after the driver leaves the route. Done means re-routing keeps the driver on a route similar to the selected alternative when that is appropriate, with behavior covered by relevant tests.
