I'm sceptical of all these official emissions figures, if they're saying it emits the equivalent of 4 average cars, then it probably emits at least the equivalent of 10-12 average cars in the real world, once you take into account all the stopping and starting.

Plus, that figure is probably an empty bus with no seats with just enough fuel to complete the test

Yeah but that bus will be there if whether there's passengers or not. A car will only be polluting if you choose to make that Journey in a car, thus instead of using a bus that's already there, you're adding extra emissions to the environment. 4 average cars sounds about right too, an Enviro 200 has what a 5 litre engine? Which is about the equivalent of 4 car engines, but more efficient because it is only powering 1 individual machine rather than 4 separate ones, not to mention large commercial diesel engines are very very efficient these days. It's basic maths that a bus carrying only a few people is much, much better than 4 cars carrying 1 single person each, I don't know where you're grasping 12 cars from, that's not realistic at all.
