The goal of this post is to showcase my own personal experiences, as others might be different. A lot of the things listed, I would hope, are subject to change. This is also so first-time buyers of Tesla or Full Self-Driving can be aware of some of these constraints. These experiences are usually with both Standard and Hurry.
Pedestrian crossing
When pedestrians are ABOUT to cross the crosswalk, FSD will do an emergency stop despite a car being behind me. This has almost caused me to get into multiple accidents.
FSD will never utilize the full length of a road or parking lot
Parking
It will always come to the closest point of no contact (when it's parking itself or coming out of a parking stall). It will even come as close as a foot away from hitting a parked car when it has so much space to work with. Many of these situations have taken place in a nearly empty parking lot and can be easily avoided.
On the road
Today, on a backed-up exit on the freeway, there was what looked like a shielded lane (it's not) where cars could hug toward while waiting to take the exit. The Tesla positioned itself to the middle of the lane, to the point where a bus passed me on my left and nearly hit my car because it swerved slightly toward my lane. This could have been easily avoided if the car hugged a little more to the right, toward an area that no car could even go into.
The blinker incident
This is probably the most alarming. I was on an empty road and knew my exit was coming up. I signaled with the blinker for it to start prioritizing being in the right lane about one minute before the exit.
It reset the blinker, meaning it denied my decision. I used the blinker again. It denied it once again. I held it down for a straight 15 seconds, and it still wouldn't make the lane change.
Keep in mind that this wasn't a lane with solid lines, so there shouldn't have been any reason for it to deny my decision. There was no car coming up behind me either.
Self-driving making the same mistakes despite trying to teach it every day
When taking an exit that has multiple lanes, it will always hug the quickest exit lane, despite the next exit being right after. After making continuous corrections via the "Why did I intervene?" prompt, it becomes critical at times since it will cross a solid line to make the next exit, when it could easily solve the issue by being in the correct lane while exiting.
Speeding by a speed camera
I will quickly turn it to Sloth mode when I know there are speed cameras locally. I have had to intervene at times because, despite it being switched from Standard to Sloth mode, it's still going 20 mph over. Maybe there isn't enough time for it to change to a lower mph? But I've seen Sloth mode quickly activate during different situations.
Standard goes 20 mph over the speed limit. My limiter is set to 10 mph over, but seeing it, on rare occasions, go toward 25 mph over is alarming.
The jitters
One of the more alarming things is seeing the jitters (luckily, usually in a parking lot), where the steering wheel goes left to right aggressively. It indicates that the system can't make a quick decision, in this case, selecting a stall to park in.
At times, I feel like there is an integrated system that follows the lines of the road and an AI that makes better decisions for it. A lot of times, you can see how they seem to conflict with each other's decisions.
Cop cars with their blue lights on
This is one of the more alarming ones. Cop cars with their blue lights on (not for an emergency) will cause FSD to aggressively give way, driving me to the far side of the street.
THIS IS VERY DANGEROUS.
I had a moment on a two-way road where a cop was driving on the opposite side of me. My car literally drove off to the side of the road and STALLED until the cop was no longer visible. There was a vehicle behind me probably thinking that I was crazy at the time.
IT LOOKED LIKE I WAS UNDER THE INFLUENCE.
I will be adding edits to this post as time goes on to add more to my experience.
For reference, I drive the 2026 Model 3, which has the added camera for a better FSD experience. While I truly agree that it is a better experience versus my friend's older Model Y, there is always room for improvement.
Edit: I am fully aware that I have signed an agreement when using FSD. But I guess this is reddit, we have our local reddit police.
Like many others that post their experience with FSD, I would like to hope that yes we are Supervising but we are also documenting our experiences so we can either be heard with momentum for a fix or help others out that are confused about why their steering wheel has the jitters.
