Something similar happened in my home town recently. The NSL (70) bypass A road was reduced to a 60mph following some accidents whilst drivers were speeding in bad conditions at night. If that wasn't illogical enough, it's now intended to be a 50mph zone following a car v pedestrian RTA.
The local community were (mostly) in uproar, calling for the limit to be reduced to a 50mph because "poor such-a-body" had died. The facts they were blatantly ignoring included:
* The person was walking down the verge of a 60mph A road bypass late night/early morning (after midnight) in darkness.
* The person was confirmed as being incredibly drunk.
* The person walked straight out into the path of an oncoming vehicle which, the police confirmed, was under the 60mph limit.
* The person died due to their own sheer stupidity.
One knee-jerk newspaper furore later, there are now crash barriers along the roadside (fair enough) but the locals are calling for speed cameras and a 50mph limit for the entire A road. That's about 20 miles of A road, off the top of my head.
This government takes the mick, but people really are dumb. Whilst people continue to be this dumb, the government will continue to be able to take the mick.
