OK. Possibly a bit contentious, but it was inspired by the speeding threads...
A few nights ago, I was 2 cars behind an old boy driving down a slip lane entry road to a dual carriageway.
He had been doing approximately 20 - 30 mph down the slip road, and a couple of drivers had overtaken him on the entry chevrons. (wrong, I know, but these things happen).
I was around 200 yards behind having dropped back to allow him plenty of room I checked over my shoulder and accelerated up to around 60 mph ready to enter the traffic stream. When I looked forwards again, he had stopped at the entrance to the first lane! I finished up undertaking him on the verge, as did the two cars behind me. The third managed to swerve into the traffic, the remainder had to brake sharply. How there wasn't an accident I'll never know.
The old boy then pulls out into the traffic to a chorus of horns, leaving us sitting there. No-one got his number and by the time we had recovered, he was long gone.
With drivers of this calibre on the road, it's no wonder people feel aggrieved at being penalised for travelling at 90+ on a
deserted motorway.
