Interesting. Here in Munich new bus stations are explicitly not in bulb form, because buses tend to pick up too much delay from morons ignoring the bus while it blinks and blinks and blinks until finally someone has the sense to let the bus merge into traffic.
On the other hand, the "blocking" way has its own downsides. I live on a 1-lane-per-direction road, directly next to a recently converted bus station - and now I have angry honking whenever there's a load of school kids or wheelchair-bound people, and morons trying to overtake the car on the other direction's lane... so far no accident has happened but I'm waiting for it.
