I think trackstands are really cool and I am always impressed when I see a cyclist doing one!!!
I am also massively impressed with wheelies! I suppose I'm just that sort of girl!!!
On the subject in the topic though - I find that I signal all the way up the junction etc but once I get there I have to drop the signal a bit and I can't pull away on the bike one handed so have to let the signal go then a bit too!
I agree that car horns scare the living bejesus out of you when you are on a bike and not encased in your car with all the windows shut!
I tend to go pretty near the white line in the middle when turning right but not right on it because the oncoming traffic can meander a little!
