At your peril!

This on Edinburgh's Princes Street, near the junction with The Mound & Hanover St., encouraging cyclists to ride between the new tramlines. I don't think so! I suppose it is marking the whole transverse zone, but could be misconstrued
My recollection of mixing bikes & tramlines, as a wee boy in Glasgow, tells me this won't work. Bike tyres and metal grooves of a similar width DO NOT MIX, I can assure you. Think again City Fathers, please.
Sorry the pic is not better, but a large bus wanted my bit of road!
