Presumably not a matchbox one
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
