Five years later it still does practically nothing. The car can’t even do the bare minimum: it doesn’t recognize speed limits on most highways in Finland because it gets confused by round LED signs showing the limit (these are used because it’s different in winter and summer). It’s just embarrassing. A self-driving car should understand road signs that a five-year-old has no difficulty reading.
I’m guessing it works better on some Californian roads that have been carefully hand-tuned by Tesla so they can show the Boss an illusion of progress.
Personally I’m not going to buy another Tesla after this episode. Optimism is one thing, but this level of hype is actively dangerous because it gives people the wrong idea about the capabilities of something they rely on in traffic.
