I spoke with (someone) at Jaunt who advised that all commuter service between Crozet-Cville is door-to-door upon request, and they have no way of knowing how long any particular route would take on any given day.
…I would definitely consider using the service if it would just be one pick-up in Crozet (say at Bank of America parking lot which is a designated park & ride) to a stop (or two) in Cville [downtown mall—UVA/Corner?].
