I suppose that was my subtext for posting (and it's representative of what happens when cycling and other vulnerable road users are brought up).

OTOH, that's a community of keen drivers, who perhaps put a little more thought into their driving than some others...

And,like this forum,a very small slice of the whole cake.
TBH,as I've got older I've become a lot less brave than I used to be,as a result my road riding has become less and less enjoyable to such a point I avoid riding on the road unless I can help it,such is the lunacy of the growing minority of drivers.

I think the keen drivers point is valid. I often notice when passed by columns of souped up hot Subarus and the like, all spoilers and extra wide zorsts, that they are some of the most likely to give a really wide pass.

Good start:

"The officers stopped several drivers for passing cyclists too closely - and four drivers were reported to the Procurator Fiscal"

but then the article goes on to explain that the four drivers were reported for document offences, nothing to do with their passing technique.

Yes, but a good start anyway.

Yes. The first milestone is to attract attention to the problem and to the available solutions. We're not going to achieve perfection in one magic step.

I had a Subaru until very recently. It wasn't "souped up". It didn't need to be - 250 BHP, 3.0 litre flat 6 Boxer engine (like a Porsche). Floor that and it shifted, I can tell you. And smooth as silk, due the nature of 6 cylinder engines. I thought it would be expensive to insure. Not so. The broker told me that Subaru drivers actually have a low accident rate, generally. They are seen as a car for "serious" drivers, because they are so well engineered. So people buy them who take a pride in their driving. As opposed to the mob that think putting wide tyres on a Corsa and drilling holes in the exhaust somehow makes then Lewis Hamilton.

Edinburgh has also taken on board criticism of usual Beware of Cyclists signs and all are now modified as shown in the second image.

Point of order.

The H6 is a flat 6 Boxer. The Porsche 911 lineage has a flat 6, but isn't a Boxer :D

In a nutshell "Boxer" engines have pistons fire such that they punch each other as they meet in the middle/head away from each other in exact mirror synchronisation, hence the nickname. Flat 6 pistons move in the same, not opposing directions.

On a boxer engine the opposing pistons move in or out together. On a flat engine they don't.
Boxers are more expensive to produce, the crankshaft is more complicated because each pair of cylinders can't share the crank pin.

You're going to have to get one of those electric cars so you can get off the line more quickly :lol:

I disagree about the taxonomy... the boxer is a type of flat engine. Another type is the 180° V.

Yes, the key distinguisher between flat boxers and flat 180° Vs is the coaxial positioning of the big ends of the pistons in each position in the two banks.
