Recently returned from Snodonia. Perhaps surprisingly, the road from Beddgelert up to the Lanberis pass was similarly marked.
The road down to Capel Curig was wider and straighter and didn't seem to need them.
On the whole drivers seem fine. There are always those who misjudge things and those who are impatient.
Then there are the idiots who think only of themselves and balatantly disregard any laws, advices or requirements that run counter to their instantaneous wishes. Thankfully they are the minority. It is for these that camera's are useful. I'm tempted to say, that when caught, a mandatory education course should be applied. But education only works on those who want to learn so no point really. So we're back to the 'smack' which, as Flecc has pointed out elsewhere, never really works especially on anti-social idiots. This leads one's thoughts to the nightmare scenario of enforced re-education. Totalitarian state anyone?
I think, just like some other recent thing
, we're going to have to learn to live with it.
