It IS actually true. It does goofy stuff in some situations, but on the whole is a little better than your typical relatively inexperienced driver. It gets it wrong about when to be assertive and when to wait sometimes, it thinks there's enough space for a courteous merge but there isn't (it does some Chicago style merges sometimes), it follows the lines on the road like they are gospel, and doesn't always properly estimate how to come to a smooth and comfortable stop. These are annoying things, but not outrageous provided you are paying attention like you're obliged to do.
I have it, I use it, and I make lots of reports to Tesla. It is way better than it used to be and still has plenty of room to improve, but a Tesla can't reboot without having a disparaging article written about it.
Also fuck elon, because I don't think it gets said enough.
