I don't think so. Even if you throw a new route at anyone like
in the past, ridership on the first day is always terrible because
most people already have in mind how they want to go to somewhere
with existing services, and when they see a new service, they will
still have to read the route map, understand and decide. Just look
at bus 88, which started with mostly single-decks on the first
day.
Also, most people are internet-literate, and that is probably the
audience SBST wants to target first and are most receptive to such
premium services.
