Thanks for the reply, that's interesting that there's so many taxis and
so many prospective passengers around at that time.

The fact that the roads are fairly empty plus higher fares is an
incentive to work, even if only for a few hours.

Of course I'd presume that London taxi drivers would represent all the
different communities in London and would thus represent all faiths,
but I must admit my (possibly quite erroneous) assumption is that many
are ethnically British white men, and thus would wish to celebrate
Christmas with their families (though of course these days I would
presume many either wouldn't regard themselves as Christians or
wouldn't be Christians, but like the majority of people nonetheless
they'd mark Christmas).

But for taxi drivers there is really no such thing as "regular working
hours" or "public holidays" because every day is a day that they may
choose to work or not work. Of course there are probably busier times
and less busy times. An experienced taxi driver is likely to know where
to go to get trade and what the best times are to work. It's not just a
matter of knowing the routes.
