Driving back home from EMA on the A453 (before it was dualed) having landed about 11 pm, so it was night. Tootling along at about 50 mph - come over the brow of the hill and there's some clown overtaking an HGV on my side of the road. Instant reaction to swerve onto the grass and we avoid by inches. All I lost was a hubcap and my composure!
