How is FSD at left turns?
Every filmed left turn, with the unprotected ones — no green arrow, oncoming traffic, a judgement call about the gap — as the hard case inside it.
Coverage by software era
How much footage exists for this scenario in each build. Eras with fewer than 3 matching videos are marked — they are anecdotes, not evidence of a trend.

Watch it happen
Worst first, newest builds first within each severity. Every card opens YouTube at the moment.

During a Chuck Cook-style left turn clip, FSD was about to drive in front of another person and most likely would have collided had he not intervened—the first such event he had seen on version 13.

While stress-testing, FSD moves into the right lane to make a left and appears about to turn in front of someone; creator calls it awful and retries.

Nav/FSD was about to turn left the wrong way onto a one-way road; he disengages and calls it the worst mistake he has seen.

Every run including this one, FSD made an illegal left from the wrong lane (same as lead cars sometimes, but also with no lead cars).

On a historically hard left turn, the car approaches too fast and appears about to turn into another vehicle, prompting a hard brake intervention; it then bails straight instead of turning.

Hard unnecessary braking, cut over lines, went through a stop sign then tried to stop mid-road with ~60 mph traffic coming; he hit the accelerator to push through.

Beta moved into a left-turn lane when they needed to go straight, likely because the road was curving.

His top safety issue on 10.69.3 is moving toward oncoming traffic while waiting for an unprotected left, creeping up to the creep limit in a scary way.

Worst moment in yesterday's video: car turned toward another vehicle instead of around it; he took over with a simple brake intervention rather than a high-speed emergency.

While going around an obstacle it suddenly decided to turn left instead—a valid route but executed at the last second in a rash way he says would scare drivers.

Prompt says use accelerator or gear stalk to continue while the car thinks the light is green but it is red; he refuses to confirm and reports it.

Downtown Ann Arbor old clip: after a left turn at a light (and one disengagement for nearly cutting a minivan), beta over-steers hard left toward the curb and he has to yank the wheel back.

Approaching a neighborhood left the car entered the left-turn lane far too early (nearby driver noticed); later the actual left into the neighborhood was excellent.

After prolonged stuck creeping and accelerator nudges at a blind left, the resulting turn is described as really terrible and is reported.

On a goofy requested left-turn maneuver, the car completed the move with no other traffic but temporarily drove on the wrong side of the road.

In dual left-turn lanes drifts too far left, forcing a big disengagement; later called one of the worst beta behaviors he has seen and the worst part of the drive.

Steering wheel moved creepily right near a curb; he accidentally took over, accelerated through, disliked the turn, and reported it.

Early beta took a left then immediately tried to dive for the curb and he saved it almost last second; present-day completes the same left and stays in lane.

Car makes a really strange left turn, rolling through what Chris describes as kind of going through a red/stop situation, though he says it handled it and he was okay with it.

She took over for a car on the other side of the dirt road because FSD moves right for oncoming traffic later than she prefers.

FSD entered the wrong left-turn lane for getting on the highway, a regression he voice-reports daily, forcing a disengagement.

Driver disengages Cybertruck FSD because it was going to turn right out in front of an approaching vehicle; FSD is re-engaged afterward.

At a tough left-turn area FSD began taking a turn that was not theirs, so he took over and explicitly called it a disengagement.

Chris disengaged to prevent an illegal left turn where cops often sit; past builds used a neighborhood loophole instead.

FSD tries to turn left where there is a no left turn sign, so he takes over and calls it a disengagement.

Was going to turn left at a right-turn-only; creator took over and counted it as an intervention/disengagement.

Nav was going to turn left onto a closed road; he takes over because FSD will drive around closed-road signs rather than treat the road as unusable, then re-enables and it reroutes.

After exiting the highway, a historically sketchy left turn was messed up again before a later recovery on green.

Still in a left-turn lane, the car wants to move right; driver takes over and lets it reroute rather than allow the move.

At stop sign car was going to go incorrectly; driver holds then allows go; he calls this two disengagements in that complicated spot.

Creator nearly took over for a left turn when the car stopped in a bad spot with traffic about to arrive; nobody was behind them so it worked, and he reported it as a driving mistake.

The car almost seemed to turn left from the right lane, then corrected, though it should have been in the left lane earlier.

With a backed-up left-turn lane the car made a dumb path choice drifting wrong, then corrected itself; the driver was concerned enough to worry about a nearby officer.

On an unprotected left it would not creep forward like 14.2 used to; Chris intervened after it risked/missed sitting through a full yellow-red cycle.

FSD enters a left-turn-only lane when it was supposed to go straight; Chris reports the mistake.

Driver manually drives to force the car straight through a construction patch instead of turning left.

FSD still struggled to exit with poor nav/phantom stop visualization; driver gave more accelerator help before it moved along with left turn signal.

At a left turn with a maroon SUV in their path the car went when the preferred earlier gap was missed; driver used acceleration boost and judged the second opportunity fine.

At closed-road barriers FSD somehow realized waiting vehicles were not simply turning left and made a move Chris called the most impressive thing he has ever seen FSD do.

Left turn signal stayed on and the mapped final destination for Pinball Pizza did not match Chris’s expected location; he suspects the business moved.

On a busy unprotected left with pedestrians, FSD proceeds through the yellow once committed instead of getting stuck as older builds did; brief extra stop for a non-moving pedestrian was suboptimal but acceptable.

Car correctly takes left-turn-only path around a closed road and handles a blinking-red light well.

A presentation screenshot shows low-level sign interpreting where FSD chooses a left turn because a road-closed sign directs left.

Took a very hard unprotected left with poor visibility and heavy cross traffic at the first real opportunity without intervention.

At the end Chris summarizes that a basic failure was not yielding on a left turn, calling that pretty sad for the state of the build.

A difficult left where V11 inches out after a full stop was handled with better acceleration and an acceptable gap, then repeated after a U-turn.

At a dual left-turn intersection that V11 almost always switched lanes mid-turn, V12 stayed in its lane and completed the turn correctly.

Difficult final left amid traffic was completed well by the car after waiting far back in the lane.
