Try going to Italy. They charge for motorways that only have two lanes (with no hard shoulder), have roadworks everywhere, the barriers are solid concrete with no regards to safety and they also have speed cameras everywhere. Most rural roads have no barriers, even along cliff edges, and the road simply drops away at the edges. Painted lines appear and disappear at random (on motorways as well as main roads).
Roads in the UK aren't great but they certainly aren't the worst.
That's an odd thing to say. The majority of Italian motorways I've driven on (all over the country) have three lanes and I've rarely encountered roadworks although that's probably just lucky timing (driving in the south of France one year I was constantly delayed by roadworks and vowed never to do it again). I don't recall driving on roads without a barrier on a cliff edge either.
Having said that, I agree with you about the concrete barriers and the lack of a hard shoulder. That can be terrifying, especially when overtaking in the fast lane. The other irritating thing about driving in Italy and France is the constant tollbooths.
The best motorways I've ever driven on would have to be in Germany. Even in the middle of winter with thick snow all over the place they're pristine and very safe and easy to drive on. British roads are OK but the thing I like about driving in this country is that everyone is generally very considerate, much more so than in other countries.
