I have the latest FSD version and I noticed that it now has a very weird behavior in roundabouts. When half way through the roundabout, it accelerates at an alarming pace, and clips the left hand curb while progressing through the roundabout. By that time I have taken over. The roundabouts in question are two lane versions.

However, with one lane roundabouts the performance is perfect...lane centering, and speed. Anyone experience this behavio

I just drove through Sedona for a few days and it has a million traffic circles. FSD did great in all of them (a mix of single and multiple lanes).

I visited Missouri this past summer and they deeply love traffic circles. Mine did fine through them. Better than me even. I don’t hit curbs, but I took the wrong exit once while old school driving. FSD never did that.

This ain’t Missouri but I bet FSD could handle it.

Yeah, like, there's no exits on it. It looks like AI.

I think it is too. Came up when I looked for the world’s largest.
I vividly remember the mayhem of Florence roundabouts with vespas and buses and shit.
there really are some scary ones. Especially in Europe.

How about the Magic Roundabout in Swindon (UK)? The quite a few 'gyratory systems', but I think this is the OG. When you're on it, it's really not too bad at all.

Damn. That’s pretty cool. Wonder how FSD deals with that.

Give me a roundabout over a 4-way stop anytime. Coming from the UK, the 4-way stops (signed or lights) are so inefficient, and I lose my mind if I get there second, and whoever was there waves me through!

I have had the same thing happen on 2 lane roundabouts every once in a while, although I had it happen a lot more in the last couple of days. These are all the slope curb, so not damaging anything, but not desireable.

I live in Colorado. When I first moved here 40+ years ago we had no roundabouts. Now they are adding them at an alarming rate. They take about 6 months to complete for existing intersections. It seems like the only guideline in their design is that no new roundabout can look like any existing roundabout.
The CT does well at most of them but at times, its behavior really scares me. If you're driving in a roundabout (called a 'traffic circle') in Colorado, be prepared to take over for FSD.

If FSD 14 fixes this, I'd be very impressed.

I have the same problem. Hoping V 14 fixes this.

I agree. I find roundabouts way more efficient than 4 way stops. So many false starts and accidents waiting to happen

I’m in total agreement, however that’s not the point of the OP. I think (hope) we’re getting close to V14, and watching Chuck Cook’s V14 post last night, it looks very promising.
