Having spent quite a bit of time in mainland europe, in a city where you get on and off any door, middle or rear, apart from the front door unless you're actually buying a ticket onboard, it really does make a contrast to trying to get from the back to the front of a packed lothian bus to alight because there's only one door rather than three. I understand that with it being about 20 years since the last time most of the fleet was dual door, there would be challenges in going back to multiple doors for most of the fleet, but it would certainly have advantages I believe.
