On the same subject, I was pondering about speeding today: a lovely day, a wide dual-carriageway that had opened up to three lanes, the fairly light traffic moving well, etc.
The traffic was flowing well at speeds of between 50 and 100mph, I’d guess, with no bunching, lots of space being left, etc. Nice and safe.
And then we came across a rare sight on our roads these days: a marked Volvo estate doing slightly under 70mph. All the alert drivers slowed down to 70mph and for the few miles until the police car turned off, it was horrible. The previously free-flowing road was now snarled up with everyone keeping to the limit and thus taking much longer to overake the slower moving commercial vehicles which in turn was causing longer queues of traffic and further bunching. It was clearly a far more dangerous place to be with so many other vehicles in a smaller area than they otherwise would be taking up.
But of course, that wasn’t the point, was it? Forget good driving: everyone was having to simply obey an arbitrary limit set in 1965 when the average family car was hard pressed to hit 70mph and even more hard pressed to slow down from that speed. Ridiculous!
