We love this video from the Look At Life series featuring traditional black taxis from the 1960s.
In it, the rigours of learning The Knowledge, passing driving tests, keeping cabs clean and various inspectors happy — as well as testing the taxi meters themselves — is explored.
Look out, too for a fascinating glimpse inside one of those classic London cab shelters.
We've always wanted to know what was going on in there.
Taxis in 1960s London
There were 6,000 taxis on London's streets in 1960s; 2,000 fewer than before the war.
Those cabs were driven by 9,000 drivers; 3,000 of whom were owner drivers. The rest worked for fleets.
Today, there are around 21,000 black cabs in London.
According to the film, in the 60s, a London taxi driver was taking 40,000 passengers a year, with the average fare between five shillings and seven shillings and sixpence.
That's between £7.30 and £10.95 in today's money, which will buy you around six to 13 minutes in a taxi, or take you one mile.
Revealed: the reason London taxi cabs are black
In the film, the narrator explains why London taxis are, traditionally, painted black: it helps make respraying and touching up easier.
Sit back, and enjoy a unique ride journey into the life of a London cabbie in the 1960s... it'll probably make you think, as you use your smartphone to summon an Uber this weekend...
