I went from San Francisco to Vegas and back last week, and it's still not quite there, but it almost there. It had problems navigating parking lots, making turns too early or too late, but the problem with it is that there's no tiny windshield wipers on the cameras. When dirt from driving accumulates on them, it can't self drive, and then you're totally lost and confused. The real problem with it though, is that because it's Tesla, it's under extreme scrutiny, so the driver monitoring is non-trivial to hack, and if you don't, you get strikes for not watching the road and then it doesn't self drive any more. Comma.ai gets to be a bit more forgiving because of how they're positioned in the market.
