Counter-counterpoint: I've been using it since 2019. I think you're exaggerating.

• It aggressively tries to center itself, always. If you're in a lane and it merges with a second lane, the car will swerve sharply to the right as it attempts to go back to the middle of the lane.

• It doesn't allow space for cars to merge until the cars are already merging. It doesn't work with traffic; it does its own thing and is discourteous to other drivers. It doesn't read turn signals; it only reacts to drivers getting over.

• If a motorcycle is lane-splitting, it doesn't move out of the way for the motorcycle. In fact, it assumes anything between lanes isn't an issue. If something is partially blocking a lane but the system doesn't recognize it as fully "your lane", the default is to ignore it. The number of times I've had to disengage to dodge a wide load or a camper straddling two lanes is crazy.

• With the removal of radar, phantom braking has become far, far worse. Any kind of weather condition causes issues. Even if you drive at sunset, the sun can dazzle the cameras and they don't detect things that they should be able to - or worse, they detect problems which aren't there.

• It doesn't understand road hazards. It will happily hit a pothole at 70 MPH. It will ignore road flares and traffic cones. When the lanes aren't clearly marked (because the paint has worn away or because of construction), it can have dramatic behavior.

• It waits so long to brake, and when it brakes it brakes hard. It accelerates just as suddenly, leading to a very jerky ride that makes my passengers carsick.

The only time I trust FSD is when it's stop-and-go traffic. Beyond that I have to pay so much attention to the thing that I might as well just drive myself. The "worst thing it can do" isn't just detour; it's "smash into the thing that it thought wasn't an issue".
