I'm confused. You seem to say any vehicle designed for more than 8 passengers can use a bus lane but you finish off by saying that that this doesn't include private hire cars. Yet you agree with cb.
cb's point was that any vehicle with more than 8 seats, including private hire cars with more than 8 seats, could use the bus lanes.
I suppose it's a question of which takes priority. I would have thought that if you take a vehicle and register it as a private hire car you enjoy both the privileges and limitations of that registration regardless of the number seats. You don't get to flip between being a bus and a PHC depending on which rules suit you at that moment.
