@OzBMR I've had enhanced AP for 3 years on my "FSD" model S and I use it all the time. It never ever did anything scary like what you're describing... and I very much doubt your narrative. Why? If any Tesla *ever* steered into oncoming traffic, there would be no Tesla. Period. It is however a well known fact that people unfamiliar with sitting in machinery operated by a non-human operator spook easily - especially if they know there is no human operator. So there's significant bias in your "experiment".
Give it another go. Make sure you are alone in the car, so nobody else is opining (or screaming) while you let the car do its thing. Learn to be ahead of the vehicle in your mind, give it the leeway you would give a learner driver, and most importantly, understand that *your* way of driving may not be as perfect as you think it is. Your lane keeping may be offset to one side and you don't even know it because you've never seen yourself drive from the outside. You may be leaving too much distance to other cars, or not enough. All factors you need to consider before you dismiss machinery that has worked flawlessy for millions of kilometres. When you feel the lane keeping is bad (and it's driving you into oncoming traffic) look in both of your rear-view mirrors and estimate the distance between your vehicle and the white lines. You'll likely discover that what you thought until now was in the middle of the lane, was actually offset towards the curb. That may be ok in some circumstances, but it's not ok if you think it is the middle...
I'd be the first to cry foul if the car ever did anything dangerous with me in it. The contrary is actually true, it's far too conservative and safe for my taste.
