Can FSD handle a roundabout?
A long-running sore point with a genuinely visible arc across versions — worth watching in order.

In a multi-roundabout mall approach with a divided entrance, the car got confused, system alarmed/turned off mid-roundabout, and he could not re-enable immediately; he planned to send the clip.

On the first FSD Beta drive the car tried to drive through the middle of a roundabout; the same roundabout now works correctly for him.

While waiting for a train at a roundabout, FSD tried to go around stopped cars and cut everyone off; he stopped it and counted a disengagement for inappropriate behavior.

At a closed road with detour signs after a roundabout, beta waited correctly for roundabout traffic then would not follow the detour and stopped, so Chris took over and did the detour himself.

At an unmapped roundabout the car takes the wrong direction; driver takes over to avoid a long reroute.

Near home, poorly mapped roundabout behavior led creator to disengage; he was unsure whether to count it and was annoyed at the ending.

Approaching home, the car took a roundabout path too fast/aggressively and drove over the curb; Chris disengaged and said he is including it.

On a tiny mini-roundabout the car runs too close to the curb for comfort and creator disengages, calling it a terrible job to finish the drive.

Driver took over intentionally to force a full-circle roundabout routing test, then re-enabled FSD.

At an empty roundabout the car stops too far back at the yield and then completely stops with no vehicles or pedestrians, so the driver takes over.

Final try for third exit failed strangely; could not turn FSD back on afterward. First and second exits worked; third was fishy.

Early beta stopped at yield signs and repeatedly failed a second roundabout by heading into the middle, requiring multiple takeovers; present-day glides yields and completes a full circle exit.

At the yield inside the roundabout, FSD goes when Chris thinks it should not; it makes it work but he calls it real sketchy and notes he should have right-of-way.

Chris describes a recurring roundabout failure where FSD tried to enter with a car already in the circle, close enough that he left a voice note saying they were going to crash.

After a complete stop, HW4 keeps an unwanted blinker on and runs close to the curb through the roundabout, but completes it; both cars later look smooth.

Moving into the correct right-turn lane for a roundabout, the car uses no turn signal and changes early across a solid line, though the following right turn is really nice.

At the stop-sign approach into the roundabout, Chris taps or nearly taps the accelerator amid left/right traffic, then decides he should not have doubted FSD.

At a stop sign into a congested roundabout FSD got stuck and too scared to go, so he gave an accelerator-tap intervention to unstick it.

Creator took over because FSD's edited route went too far out of the way; he redirected into a parking lot to retry the roundabout and said it does not count as a disengagement.

At a Michigan roundabout FSD misses the intended exit (likely treating it as blocked by a co-exiting car), stays safe but adds about three minutes to the route.

At a roundabout used to trip the car up, it signaled right as if for the exit then wanted to go all the way around; he manually turned it around.

Creator planned to take over after the first exit to send the car around the roundabout and later manually drove while setting a more interesting highway loop destination.

Second roundabout attempt: car is hesitant and stops while a driver waves them on; Chris taps the accelerator as an intervention and says roundabout trajectory/speed understanding is still off.

After an inappropriate mid-roundabout lane switch, someone is present and he has to hit the brake because the car was continuing and not braking hard enough.

At a yield/roundabout the car stops when it should continue; he presses the accelerator, it surges then goes very slow, and he reports the sketchy roundabout behavior.

Driver briefly took over to force the last destination through a roundabout, then FSD handled the roundabout perfectly while waiting for a pedestrian.

Another roundabout required an accelerator press; car also changed lanes mid-roundabout and slowed significantly.

Chris had to press the accelerator once on a later roundabout and said it felt a bit like a roller coaster.

He let it start the roundabout then took over to go the way he wanted instead of all the way around.

At a roundabout the car stops at a yield when it should not, then proceeds after correction.

Car stops at roundabout yield (still treating yield as stop); driver taps accelerator because someone is behind.

Car tried to exit the roundabout to the right with no destination set; he took over to go left instead.

Around a roundabout destination that previously sent the car into the wrong parking lot on earlier software, 14.3 handled the left turn and entered the correct lot.

FSD started braking in a roundabout despite having the right of way; he reported the behavior and noted another driver then cut them off.

He is impressed with version 14 roundabout handling versus older versions, and notes a really aggressive but nice unprotected left turn.

FSD drove roundabouts assertively and smoothly, which Chris said felt really good.

The car flies through three formerly difficult roundabouts when clear without the hesitation and honks he saw on version 13.

Took the full roundabout path instead of the expected exit and executed it perfectly before turning into Costco.

Roundabout decision-making was good overall but steering was briefly twitchy/unsure on one entry.

Car correctly yielded, then handled a roundabout without issue.

Through a tough multi-lane section with a vehicle in the blind spot also going straight, FSD stays in lane and handles it very well.

Right turn signal in a roundabout comes on early and may have confused a waiting driver; otherwise roundabouts are handled well.

At a roundabout FSD stayed in the correct right lane and accelerated out cleanly.

Roundabout with a blue truck is handled perfectly with no intervention.

With traffic in a roundabout it waited longer than he preferred, then took an opening that he judged not awful.

In a downtown roundabout the car went too slow and stopped when it should not have.

After being guided out, it smoothly handled the roundabout (including past a Rivian towing); passenger was anxious but it did great.

With sunglasses on and attention monitoring off, FSD handles a roundabout while still not immediately nagging for hands.
