Yes, London buses consume a large subsidy, but it doesn't come from the

have made it worse, being almost twice as expensive as conventional hybrid
double-deckers, heavier on fuel, and with a fare evasion problem. London

Given even the normal hybrid buses I occasionally use only seem to switch
their diesel engines off when stopped (might as well just use a stop-start
system rather than lugging heavy batteries around) and for about 3 seconds
after pulling away I wonder who much fuel any of them really save.
