Usually I do because it is harder for them to find a decent gap in traffic due to poor acceleration
Anyway I saw this bus on the side of the road ahead of me and a guy who just hopped off. I backed off the gas expecting The bus to pull out but he didn't nor did he indicate. When I am closer, close enough that it makes more sense to go past than giveway he starts indicating then as I start to go past he moves into the road making me move slightly over the centre line.
