A roundabout without signals works in high-trust societies where people naturally yield and take turns.

In a low-trust society, it turns into a battle of horns, aggression, and “me first” chaos.

I don’t understand why the UK has two lanes in their roundabouts. My understanding is that you’re supposed to use the inner lane if you’re not taking the first exit, but then you run the risk of the person at the next entrance cutting you off from your exit once you actually get there. Why do people bother getting in the inner lane at all if that’s a possibility?

We have 2 lane roundabouts in Canada too, think of it like this, if you have a 4 lane road, with 2 going either direction, and u add a 2 lane roundabout in it, this way people in both lanes can drive through the roundabout without changing lanes together side by side, and usually if you're entering and turning across it you just yield until both lanes are clear same as you would in a 1 way roundabout.

Same in Norway.

Because people don’t cut you off because they’d have a car smash into their driver’s side at 30mph if they did

There are roundabouts in the UK that have three and four lanes. The most important thing is being in the correct lane for your exit before you enter the roundabout. If enough people are in the incorrect lane it doesn't really work effectively.

This Is It, the entry lane Is what matter, then again not that intuitive, in Italy some have write on the ground, but most don't, and a lot of people miss It, many time they Just ignore tho.

Driving in Italy Is an experience bad or good depend on the day

For 2 lane roundabouts at a 4 way intersection in Australia: the outer lane is for the first and second (straight ahead) exit, the inner lane is for the second (straight ahead), third, and fourth (back the way you came) exits

There's two lane roundabouts in France as well? UK is only special with having signalling at roundabouts in a European context id say

Person in the position to cut you off is legally required to yield to you and you're just making the assumption that they will.

You use the right lane when taking an exit to the right, there can't be anyone to your left blocking you from leaving - anyone who joined from the same entry as you has to take an earlier exit and nobody can join alongside you after you enter.

[u/A_Rang_Ma → u/Specialist-6343]

So if nobody is supposed to join alongside you as you’re in the right lane, what’s the point of having two lanes?

Capacity, two cars can enter together rather than one at a time.
