I don’t know anything about the concrete central barriers…other than they are popping up everywhere, but the old Armco (?) metal ones were designed to give and gradually return you to the driving lane (with a ****ed up car, but at least safer for you) How are the new ones designed to work? EDIT - They’re Jersey barriers apparently (although aren’t made of wool) and last longer than metal ones. https://www.clearway.co.uk/news/what-is-a-jersey-barrier/
The country is bust, too much waste and not enough tax being paid/collected. On the M1 yesterday, potholes all over, the joins of tarmac splitting open, debris all over, next to the central barrier full of accumulated grit and gravel and now growing grass and weeds, and probably worse of all puddles of water because of subsidence or more likely the surface not laid properly. Oh I forgot using what was the hard shoulder as a live lane and ****s who sit in the 3rd of 4 lanes, the standard of driving these days is appalling
