Artic buses are bad for the environment wether they they are electric hybrid or not
Bus stop capacity bus station capacity eg difficult in most bus stations
And secondly they take 2.5 times of space on the road which if I remember rightly why Ken livingstone and Boris got rid of them in London due to length etc
It was worked out that a double decker bus was more efficient and effective
Only benefit to having a bendy bus is if you use it on a route with low bridges where a double decker couldn't be used but we have little issue of that on "core" routes in the North East
