Filtering on the M3

My story occurs on the M3 northbound.

I’m chugging along between the outside and middle lane, the cars almost stationary.

The traffic thins for a few hundred metres as the cars in front close up and we all start to accelerate.

A chap in the outside lane seems determined not to let me pull in front of him so puts his foot down harder and harder, keeping alongside.

The inevitable happens, I slip between the now rapidly slowing lanes of cars, he rams straight up the back of the car in his lane….
