Refuges do get used, and often abused - truckers taking tacho breaks is common.

I refer the honourable gentleman to my earlier response. So how would the non-t.i.c part be achieved? Nope. You've lost me. Perhaps something a little less cryptic might get the sort of response you are looking for? Perhaps re-read what *you* posted to save me the trouble of one-finger typing "...

I think they are a fantastically expensive solution looking for a problem. They're a way of adding lane capacity, with the enforced variable speed limits reduce speeds to improve the time separation between vehicles. If you can suggest another way of achieving those aims without using additional la...

No-one in lane 4 on your smart motorway?

Your point about lower speed limits on congested stretches increasing time separation interests me. I've noticed what feels like higher traffic density, with smaller distance separation, when lower limits were in force, although what is cause and what effect I cannot know. Next time I'm on the M6 I...

Unlike black cats at night, the grey ones are sometimes yellow

Smart motorways often have average speed cameras... Which ones? David If they're the (often yellow) ones on the posts, pointing towards the sign gantries, then they're 'spot' speed. Average speed cameras are usually one camera per lane, on separate posts, they'll be at regular intervals and at junc...

They're a way of adding lane capacity, with the enforced variable speed limits reduce speeds to improve the time separation between vehicles. Do the variable speed limits achieve that, though? Or, more precisely, does the way they are enforced achieve that? Enforcement won't change actual behaviour...
