If you do any distance driving up and down the country’s motorways, then you’ll know about the “keep apart two chevrons” markings that are being painted on the roads these days.

When driving along, these look reasonably small and square, but it’s actually an optical illusion. We stopped alongside some of these markings on the A34 northbound last week. What you don’t appreciate at 70mph is the fact that they’re actually over 7ft long and very much longer than they are wide.
Have a look next time you’re driving over them – they certainly don’t look that big.
