Anyone who claims that FSD doesn't work is flat out lying. I've used FSD 13 for almost all of my driving since it came out last Dec. I've used in in cities like Boston and I've used it on dirt roads in Vermont and Maine. I've used it on highways and on mountain roads. It's worked in the rain, snow and fog. I drive up Cadillac Mountain Maine in the fog. It's stopped for deer, twice, it's stopped for a e-scooter rider who shot out into the street without looking, I would have hit him had I been driving but FSD has faster reactions than a human and more and better sensors so it stopped. It does make mistakes but none have been dangerous. There are some anomalies, for example it swerved around a squished animal but not a pothole. At this point I feel much safer with FSD driving than by hand driving. Humans only have two eyes, FSD has cameras on the fenders, the B pillars and the rear as well as the cameras on the windshield and it's looking at all of them all the time, that's impossible for a human. The cameras also see better at night than human eyes.
