I'm sure I heard something about this a while back... maybe it was somewhere else and now they're rolling it out to more places? I seem to remember seeing it on breakfast telly.
Stupid idea.
But then, people who speed through our villages are ignorant sods. What makes people figure that the 30 sign doesn't apply to them, so they continue travelling through our villages at over 70mph?
Maybe it might slow folk down a little, without tying up police time, who can go hoodie-hunting or something?
I think the reality is more likely to be as BSH suggests however, and there'll be a sudden increase in the number of little old ladies being bashed instead.
