I happen to like the beautiful symmetry of your junction, if only more were so predictable, eh?
In terms of being "frankly a bit scary to drive around" though, these two are a little more the thing...
The first is "Spaghetti Junction" on the M6
5230'40.47"N
151'53.22"W
The second is "The Magic Roundabout" in Swindon, which I'm told flows smoothly even in heavy rush hour traffic. Until some outsider who doesn't know the junction gets confused and causes a fifteen car pile-up, of course

5133'46.09"N
146'15.64"W
Cheers & God bless
