Bluecruise exists it works, it's generally safe. If you try and kick this back and say it's not Full Self Driving or comparable to Tesla, then I'm going to start posting links to videos of Tesla FSD (All generations, including latest) doing thing like ignoring school buses signs and mowing down children, turning off with no warning at highway speeds, and otherwise dangerously not-working.
You can try and claim Tesla's self-driving features are great and work 100% of the time, I suspect most people here know that is FUD and there is ample evidence that Tesla "FSD" is certainly no better than competitors and is arguably worse.
