Honking Buses

I have noticed that very few indicate when pulling out of bus stops though, which is annoying - We can't tell if there are still people getting on and by the time you start to overtake there's a fair distance to cover before you clear the bus. Meanwhile he starts pulling out...eeek

it's quite simple if you see passengers on the pavement queuing to get on, then they are still getting on, if there is no one, (or they are all leaving the area) safe to assume they are about to pull out.
