Still shaking and fuming about this...
I took my daughter for her post-lunch nap in the trailer around the seat this afternoon - very windy and exhausting but great as usual. As I was returning along Holyrood Park Road here:
as there were many cars parked in the left lane, i shoulder checked and saw nothing coming so moved in to the right lane. As I do when with the trailer I kept looking over my shoulder, and saw a black Audi (possibly A6 I think) approaching very fast, and decided to seek refuge on the left - the car missed the trailer by literally inches and I let out an involuntary yelp. 15m later at the red light, with the car in the left hand lane as I pulled up in the ASL to go right, I got a barrage of incredibly threatening abuse from a very large man who told me to be over on the left. I was incensed and quoted various highway code/bike ability things at him and asked him for his references for this advice other than his own bigotry. I forgot to say anything about the fact he was approaching a red light.
I have not yet been this scared by a car when pulling the trailer - nor have I been as as sure I was going to have to physically defend myself and my daughter. If it came to that I'd be about as much use as a blancmange... the man is incredibly threatening - I didn't get the reg number (very annoyingly).
Wingpig gave me excellent advice which was to appear exasperated rather than angry - and I gave that a go, and it may have saved my bacon. I don't need a reason to cement my belief in movements such as Pedal on Parliament, but this sort of behaviour and occurrence is depressingly all to common.
