Well, I say SMIDSY. I doubt he could have missed me, I was wearing a fetching high viz jacket and waving my arms around like a demented seagull just before he decided to turn (I had a distinct feeling he was going to pull this stunt). So less SMIDSY, more "I've seen you are don't give a f*ck".
Presumably he is of the "well I didn't hit you did I" brigade. The reason he didn't hit me is that I saw him, took note of his actions, and slowed as it was obvious he was an idiot.
