I've just realised I've been driving 30 years this year and can't remember a cyclist lurching in front of me with no warning either.
I suppose it must have happened. I've certainly seen plenty of less than brilliant riding and a few occasions of aggression - I've mostly suffered from that as a pedestrian, because that's the only time I'm weaker than a cyclist.
But I've seen the same from drivers too - including lurching across my path without warning.
What I do definitely remember is about a year after I passed my test, just at that stage where you lose your fear and start to think you're really good, I pulled from a side road across the path of a cyclist.
I saw him but I misjudged his speed and do you know what else? I somehow thought he didn't count as much as a car. Not that I wanted to kill him but I'd have definitely waited if he'd have been a car because I respected cars more.
He went fucking mad at me and he was right. I cringe to this day. I wonder if he's survived unscathed.
I mostly walk or use buses or taxis now.
When I cross roads I look carefully, including over my shoulder and watch out for cycle lanes.
The Tufty Club made a very big impression on me when I was growing up and I'm very socially aware
.
I always get a secret thrill when I do it and see the look of utter disappointment in the eyes of the self-righteous cyclist or driver who was longing to toot and swear at me but has been cheated by my desire not to get squashed 
There are quite a lot of you about. Motorbike riders are generally pretty good though, aren't they? Not that I'm one.
