NCN5 performs that manoeuvre opposite the NIA here in Brum. It's the final insult after all the muddy towpath, wharfs and RADAR gates from Smethwick. No comedy magic paint, though for silly sign value there's one of those Sustrans wiggly posts pointing the way up the stairs.
Fortunately, if you're no more than 2mm wider than an ICE Sprint and have really good spacial awareness, you can squeeze past a bollard and take a long-cut via the NIA's service ramp.
