The fact that you have to pull over to the hard shoulder, get your calculator out and remember something you were taught in school (assuming you were in attendance that day) before you can work out what the damn things mean only goes to prove my point that they are a complete waste of paint.

It should be bloody obvious what they mean. For a sign or road marking to be useful, it needs to be either so obvious it's not open to interpretation or something that's so ingrained in our culture (such as a red light or no-entry sign) that there's an immediate association. These markings and their associated signage are an epic fail on both counts, IMO.

I see it exactly the same way as Silk.

Err, the whole point of number lines is that you don't need a calculator. It's a way of teaching BASIC maths at primary school!

With cars moving it is impossible to have any accurate method...
So I think there is some value in that it makes people think about distance, but it has no clarity

I'm assuming that as soon as the chevrons end it goes back to one car length.

Someone has to keep you lot from killing each other.

It was a long time ago, but one night when I was browsing YouTube out of sheer boredom, I found a series of YouTube videos posted by the Highways Agency or something, and they were basically giving tips on how to manage various different situations.

One of them was talking about safe motorway driving, and it had a section where they showed you what to do when you encounter these chevrons on the motorway, and the whole idea is that you're meant to keep two chevrons in full view at all times between you and the vehicle in front.

Meaning, when you cross a chevron, ideally, the vehicle in front would be beyond the 3rd chevron ahead of you, if that makes sense? Basically, make sure there are two clear gaps between chevrons in front of you, kind of like this picture shows.

Which is exactly what GTR1400MAN has been saying about the operative word in the sign being "KEEP" two chevrons apart.

There are more likely to be collisions whilst people work out what a chevron is.
