That's ironic, because virtually everyone who performs a banned right turn
is committing a deliberate crime, whereas virtually everyone who goes
through a No Entry sign (except at this junction) does so by mistake.

Not here they don't - there is a very silly little bit of one-way street
outside my block of flats that serves no conceivable purpose except to
make life difficult. And it is widely ignored, or else people simply
reverse down it - it's only about 25 yards long.
