I swear I saw this while a passenger in a car today. The pavement now has bollards with signs for a human & a cycle on each one, so presumably it's for both. When the pavement got to a road junction, there was a freshly-painted triangle & set of give way lines on the pavement.
Presumably this means the new rule of 'cars must give way to pedestrians & cyclists when entering or leaving side roads' has been reversed here - but only on one side of the road, because there were no such markings on the other pavement.
Has anyone come across this? It's in a local authority area in which the highways department has historically been somewhat creative in its use of road markings, hence my feeling that it's not normal usage.
