Exactly my point. Deckers don't need to be DDA. And I doubt that in the real world anyone is going to be worried about even a single decker going round with no destination for a day or two until it can be fixed. Anything is better than a bus being cancelled. Yes it's reasonable to expect wheelchair access, but many of the DDA regulations are obsessive pedantry and are unfair expense to small operators trying to run buses where everything favours the big guys.
