[1] I have a very vague recollection of having seen bus stencils
somewhere in the UK. Bike stencils are provided in places though,
unlike some other places, there is no stencil on the red lens.

Birmingham, at the junction of Longmore Street and Belgrave Middleway.

Buses and Bikes can go straight on from Longmore Street into Horton
Square, cars can only go left. There's both a bus stencil and a bike
stencil, and bizarrely they have separate lanes.

The layout is hideous, as the dedicated bike lane to cross the
Middleway heading north is in the middle of the road and the bike lane
runs along a widened pavement to the west (where you'd expect it) and
then crosses into the middle of Longmore Street unprotected (where you
sort of expect it). But coming from Horton Square you end up again in
in the centre of the road and are expected to move right, into the bi-
directional bike lane, unprotected. So you have massive traffic light
protection for a move across Belgrave Middleway, but fifteen yards the
other side you have to make a weird, unprotected move which drivers
won't be expecting: from the perspective of a driver heading north,
they'll confront oncoming bikes heading south in the middle of the
road crossing to the western side of the road.

This is part of National Cycle Route 5, and is the recommended route
to cycle from the South West of the city into Birmingham (along Gooch
Street) and is also a useful route towards the Grand Union at Camp
Hill locks (cycling on belgrave Middleway is hard work when you can
cut diagonally across). I just get in the bus lane and behave like a
bus...
