I really like the concept of 'little & often' but wonder how many full buses will pass commuters stood in the rain at peak times. 

I hope the use of Sprinters in some way leads to sustainability of rural or marginal services. It could even be a window into 'taxibus' type services for depots that usually operate only larger vehicles. The Sprinters could then be utilised during the evening to reduce fuel consumption when passenger numbers are low.
