Precisely. I notice that most of them are now six-wheelers, with some double-deck six-wheelers that look like refugees from Megabus. The climb to get into the single-deckers must be a real problem for people who need level-access. I can see the point of such large vehicles to a certain extent, especially for the section up the A90, but trying to fit them through country roads must be a nightmare. Still, with the distinct lack of country bus designs, I don't think there's any alternative.
By the way, Clot of the Week award to the First driver who took his double-decker down a tiny road into a car park at Aberdeen Uni on Sunday. He turned left before the traffic lights on St Machar Drive instead of after, and nearly ended up going under the extremely low arches between the two halves of the Taylor Building. A very surprising sight for someone going off to do a bit of revision in the computer room near by.
