Impatient drivers who have to wait for 30 seconds or so for a bus to pull away from a bus stop. 400 bus stopped at the bus stop outside the dentist in Colinton Village just before the corner/bend leading to bridge heading to Gillespie crossroads. I stopped behind it as I was not prepared to overtaken a bend where I couldn't see what was coming. White van man behind me, sounds horn, rises his hands and shakes his head
