It was an official campaign but it’s worth noting that the satirical element of it is there, deliberately, because we are way, way funnier as a nation.

Almost nobody worries about these transport safety cameras because we don’t fear or tolerate overpolicing in the same way.

Of course there should be safety cameras on public transport!

And if a US tourist was on a night bus in London they too would be happy there were cameras. A nation of drivers has a very different calibration, I suspect.
