I also did https://app.asana.com/0/555089885850811/1209078853452832/f as that needs to be shipped with this change.

It works!

I notice you deleted the old trip plan controller but stopped short at removing corresponding trip plan view or the associated templates, how come?

I can remove most of those too, but we still use some code from the view. I can remove the rest, but really only removed the controller because it had failing function calls like trip_plan_path.

It does the job! There's so much more to clean up, but that can be done in a followup.

This is pretty exciting!

Non-blocking nit: I think we also want to remove the trip planner preview from the admin page. Non-blocking because that is low-impact and could easily be done as a follow-up.
