Does FSD slow down for speed bumps?
The comfort problems that do not show up in safety statistics but decide whether you actually use FSD every day.

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

Car hit a crazy pothole on rough Michigan roads; Chris notes pothole avoidance is a regular critical-intervention issue especially on dirt roads.

Bug where the car stopped on train tracks; Chris called it really bad and said it sometimes stops too far back from a stop sign.

He calls a big disengagement after FSD fails around a stop/construction situation near people and train tracks; he reports it and later takes over for a really bad job.

FSD drove toward three large potholes in a row that could have taken out a tire; the driver intervened and later reported it.

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.

Near train tracks with two red lights in a row, the car ignored the first red light and would have driven through it, treating the second light as the one to stop for, so the driver took over.

FSD tried to turn right on red despite a no-turn-on-red sign, so Chris stopped it and waited for green.

On snow-covered dirt road with no lane lines, the car drifted too far to the edge and registered a phantom speed bump, so he turned FSD back on after takeover.

At an intersection requiring stopping far back for train tracks (stop here on red), FSD did not stop at the correct line so he stopped and planned to report.

With no destination at a dead end, car chooses right while driver wants left, so driver takes over.

The car hit neither a huge pothole nor clearly avoided it, with the creator noting it did not hit it but also did not avoid it.

FSD missed a pothole and the back tire hit it.

FSD barely clips a large pothole edge and rides a bit of curb; creator hits the report button but does not count it among the two interventions.

On the V12.1 test-loop ride, the car braked a little late for a speed bump when no other traffic was around, but still braked in time at an appropriate speed.

On a recent personal road trip, the creator says his Tesla would have hit big potholes or possibly slid in snow if he had not been supervising instead of looking at his phone.

The car appeared to head toward a mailbox as if it would hit it, then corrected; Stephanie thought Chris was dodging a pothole.

He fully took over for large potholes the car appeared not to see or avoid, including some in Ohio bigger than the car that it would have driven through.

FSD incorrectly stops as if train-track lights were traffic lights amid construction and a flagger; Chris presses the accelerator as an intervention and notes they briefly go the wrong way on the road while FSD recovers.

In 35 and then 25 mph zones the car went about 43 and 41 mph; creator used the right scroll wheel to set Max to 30 and counted this max-speed change as an intervention.

He changes the route mid-drive and calls it a technical speed bump while noting many early route edits.

After reading a 40 mph sign, FSD stayed around 26 mph in a 40 zone, so Chris pressed the accelerator to reach the limit.

Both say potholes are largely not avoided and speed bumps are hit-or-miss, so drivers must take over to avoid them for now.

Creator hit the accelerator after the car wrongly waited as if train-track signs were stop lights at a spot it usually handled.

Heading toward a neighborhood he bumped the speed up because the car was going too slow.

FSD moved over somewhat for police and drove through a large pothole that he reported, noting pothole avoidance is still coming soon.

FSD handled a speed bump well and slowed/moved for a pedestrian.

Chris noted a little pothole while discussing Grok not yet controlling the car.

FSD slowed appropriately over a speed bump in a way that felt great at the speed it used.

Nice controlled slowdown for train tracks with no brake stuttering.

He notes FSD still aims well at a large pothole.

In a parking lot it slows for a large road drop/bump he did not even notice.

FSD slowed appropriately for train tracks and the creator said train tracks on this version feel pretty good overall.

FSD does a nice little slowing for train tracks while hands-free is active again.

With the road wide open after a complete stop, FSD kept creeping with its nose in the road and also went straight for a pothole; Chris called it too timid and second-guessing when no cars are present.

Entered left-turn lane naturally, waited appropriately near train tracks/Corvette, then took the green well.

On assertive, FSD largely ignored a speed bump that chill and average had slowed for on the outbound pass.

The vehicle slowed for some speed bumps in the employee drive, called a big improvement for people whose V11 ignores them.

He is impressed that it stops before train tracks (possibly due to a line or other cue).

Unprotected left was good; train tracks were handled but slightly close to another car, bumpy, and Chris reported wanting more slowing for tracks.

Stops before train tracks then creeps through the right-turn maneuver without stopping on the tracks; handles cones calmly.

On a dirt road, the car still does not avoid potholes while new deceleration chevrons and stop-line visuals are shown.

The car completed the interesting multi-turn sequence Chris expected to be difficult, including complete stops and good pathing near train tracks.

Stopped at a dirt-road stop sign with no line, took a right then immediately signaled left, handling potholes well in the rain.

Car avoids a big pothole well but then drifts too far over and wants to drive into a parking lot, creating an uncomfortable situation.

He saw a speed-bump visualization on the display when there was no actual speed bump.

Visualization showed a nonexistent speed bump, then the car stopped and perfectly waited for a pedestrian who walked in front and waved.

Car moves far forward for a left and makes a perfect turn while also avoiding a big pothole.

Car handles railroad tracks fine, briefly slows to 53 mph, then preemptively slows for a red Jeep exiting a parking lot that might pull out.
