I've thought long and hard about this and the only conclusion I can draw
(apart from some of the Golden Tours buses which seem to require the

entertain the drivers (although I also feel that annoying locals keeps
the drivers entertained too)

Its probably something like that I suppose. Though you'd think the constant
engine noise would eventually **** the drivers off too if they're trying to
relax.
