It's probably more confusing for people who drive on the right (which is the majority of the world's population).

What I don't get however: is there really so much traffic there that a single big roundabout wouldn't work? I mean, it apparently works in other places (https://en.wikipedia.org/wiki/Place_Charles_de_Gaulle#/media...), although that is scary as well...

For the longest time yeah, it was the centre interconnection of all major routes though the town centre. If you look on street view you can see the main arteries working out from there to the older parts of the town (ignore west and north neither existed in the 70s.)

I think it will predate the M4 and A417/9 build dates just, 100% predates Thamesdown drive so you didn't have good circular options around the town.

Thanks for posting the giant roundabout. Whatever is happening in the original could’ve been avoided entirely.

My state and surrounding counties have been on a roundabout build spree and it’s really awesome. The only one near me with 2 lanes on one side hand to go back down to single lanes because drivers couldn’t understand one lane was for going “straight” and one was for looping around to another exit.

Here in Lithuania lots of Turbo-roundabouts were built lately, I my eyes it the best way to connect multiple lane roads as it's pretty hard to mess it up - bumps on the road itself help to direct the traffic (and, of course, signs when entering help too).

Same roundabout came to my mind.
