Unfortunately these signs are now in very common use to indicate a "Bus Gate", and are enforceable as Bus Lane offences. The signs are very clear in the photo.
In the 50s when ships were equipped with radar, there was an expression "a radar-assisted collision" where two ships saw each other on the radar, but seemingly ignored what they were seeing. It looks like we have a new phenomenon of "Sat-nav assisted PCN" as we see so many threads where this is a theme.
Did you not understand what the signs meant, or just didn't notice them ? Whilst you can submit reps, you need a credible theme, and I don't see one at the moment. Hopefully, others may do so, so wait a bit before paying.
