I’ve been using FSD for the last 6 weeks. Paid for the monthly subscription, and running v12.3.6 It’s almost killed me once, when it was about to blow through a red light at ~70mph, while a car was about to turn left in front of me. There was no indication that it was going to stop, so I slammed on the brakes. Then, after about three weeks, it stopped tracking the lanes properly, and would drive straddling the lane divider. I’d repeatedly enable it when I was in the far left lane of a 4 lane road, and watch as it would promptly begin driving about two feet into the right lane. Disable, and reenabled and it would repeat this engineering feat. It continued for 2 days. Yesterday it was just driving extremely right justified. If there were any cyclists in the bike lane, my mirrors would be intruding into their space. Of course I bought the FSD function as I knew that I would be attentive and provide feedback, kind of a service to humanity, as this feature is far from prime time, and isn’t safe. I may cancel the service as I’m concerned that my 17 year old new driver will enable it, and not be as attentive.
