Now I've seen it all...
Riding at 20mph+ in secondary, nowt coming the other way. Nice wide SC road albeit divided by long hazard lines, in a 50mph zone. Micra behind begins to overtake, like it is allergic to me, right on the far side of the road, but without a gear change down so passes doing about 5mph more than me.
There is a revving engine closing fast behind me, the Micra is still on the far side of the road about two bike lengths ahead of me, a Golf appears alongside of me, slowing sharply, it goes down a gear the engine is gunned and Golf attempts to undertake Micra. But Micra has started pulling over to the left and just as I'm thinking "Kaboom!" Micra spots Golf and steers abruptly to the right again. Golf roars through gap and completes undertake. Micra slowly pulls over to the left by which time an Audi is overtaking both me and Micra.
Outstanding.
