"Oh Shit" moments...

Your welcome :o) , what did you actually say to them? People who are walking may not necessarily be in any particular hurry, and whilst chatting to each other might well just stop at the kerb and finish the topic of their conversation before concentrating on crossing the road, its better than stepping off the kerb mid flow without looking/concentrating as some others do. Also maybe you look faster than you are so they thought they had to wait ;-)

They weren't talking to each other though, which was the weird thing. I could see them from some way away and they just stood silently, motionless watching me for about 400 yards. Quite weird.

But then when I was having a shower later I imagined skidding in circles all around them and making revving noises and all was better.
