If I could interrupt there for a second—sorry, I only have a couple of minutes left—I want to ask, on that point, about operational costs versus capital costs. My view is that there are successful models. Should this not be a user-pay system? Why should the federal government be responsible to help with operational costs?
In the time remaining—because in your testimony you talked about on-demand services—I'll ask how that would compare to on-demand services. I could take an Uber instead of a bus and obviously that's more pricey, so where's the sweet spot there?
