It wasn't close or scary or owt, and I'm 99.99999% certain it wasn't an actual 'chicken' situation (if it is then he lost badly).
Riding down the right of the traffic towards Tollcross from the Meadows, well in on my side of the road. Notice a car coming the other way swing over the centre line. Not a drift, a very deliberate motion. It almost immediately swung back to the correct side about ten yards before me.
Got a good look at the driver - a 'yoof' in a beanie laughing with his co-pilot while looking at me. Sadly all over so quickly there was no chance to get the plate - the road in his direction was a clear 30mph and a chase would have probably made him laugh even more. All I got was it being a blue Polo (an' dis iz how I knowz dey is gangsta innit in a motah like dis).
Not exactly something to get the heart pounding even a fraction quicker (I had plenty of running away space to the left as the traffic moved to that side to go through Tollcross) but just another of those little irritants that show there are a lot of people, and a lot more young people coming through the driving ranks, who see the car as some sort of toy.
