Just this afternoon I witnessed an accident that shows your arguments for having imperial and metric side by side to be completely fallacious, and in fact are dangerous. At around 16.30, I witnessed a van crash into a low bridge (this was a low bridge I reported on not so long ago, where dual signs reading 2.4 m and 7′-9″ replaced an imperial-only sign, and which had drastically reduced the number of vans crashing into this bridge).
I called the police, who asked that I remain on the scene in order that I could give a statement. Eventually a policeman on a motorcycle arrived, and, after extensive interviewing of the van driver (who miraculously was not hurt, thanks to his seat belt and airbag), finally took my statement. I asked the policeman what he thought was the reason the van driver crashed into the bridge, as the sign is quite clear. The policeman’s reply was that the driver saw the sign clearly enough, but, in the heat of the moment, confused the feet with the metres, and read the sign as 7.9 m.
You may say that this should not have happened, but lots of things should not happen but do, and metric-Imperial mix-ups are all too common. Your arguments for retaining Imperial, as evidenced by this accident, are a danger to the safety and well-being of British society, and, I would respectfully suggest, are not something you should be proud of.”
