What's the most dangerous U.K road you have driven on?

Just wondering what the most dangerous road you have driven on is. The road that made me nervous was the A77 into Glasgow, many years ago it was the A77 but it's now the M77. The road consisted of two lanes northbound and two lanes southbound, nothing unusual in that except the only thing separating the two, A DOUBLE WHITE LINE!

Now obviously the road has been upgraded many years ago to motorway but it begs the question, who in their right mind would be happy to let the public take their life in their own hands on this road?
I've travelled this road many times and it wouldn't be the first time I'd witnessed morons crossing the solid double white line to overtake, madness.

A537 Cat & Fiddle before the average speed cameras went in. Only realised this when I progressed from being a young boy racer to more responsible petrol head!

Now not keen on M6 between j19 and j16 - but that's because of idiots - Smart Mororways should help a bit though.
