I am in love with Enormo-Cob too...
Another car-based Karma.
We used to live in a place where, because so many accidents had happened when people tried to pull out into a main road with zero visibility, there was a small stretch, maybe seventy or eighty yards, of one-way street between the main road and the estate. It was clearly marked at the estate end with two no entry signs and a huge white No Entry painted on the road, but every so often someone would think it worth while to break the law and drive the wrong way down it to get to the main road sooner.
Because it was on a road used by primary school children on the way to school (this was in the days before every child was taken to school by car, so there were quite a lot of them walking along that road in the mornings and afternoons) all us mums frowned on this: we knew the children knew it was meant to be one way and so only looked in one direction before crossing the road, no matter how often we told them to look left-right-left properly...
So one lunchtime when a nerk in a fancy car came along that road the wrong way I stopped crossing it and stood in his way, gesturing at the signs and the road marking and making "stop" motions at him. Rather than slowing down, he accelerated straight at me, and I had to leap for the pavement.
As I picked myself up and started to turn to see if I could get his number, there was a squeal of brakes and then the crash-tinkle of collision, and to my utter delight the next thing I heard was a slow, measured police-voice (we all know that voice, they do it when they have got someone dead to rights) saying "Excuse me, Sir..." The cop had been coming round the corner into the road in the right direction when Nerky McNerkface drove straight into the front of his panda-car.
I didn't wait about, because I didn't think they needed me to be a witness; I went into the shop next to me, where I knew the owner pretty well, and we leant against the counter together and howled with laughter. He had seen it all and been on his way out through the door to get the nerk's number, and said he'd never seen such instant poetic justice.
