I was being a bit tongue in cheek about the learning and the teenager. However as each car operates using an on chip neural net which is ‘trained’ by the software updates, yes in effect there is some semblance of learning on car. However the big hops in knowledge are gained through the software updates. The biggest thing to get your head around is shadow mode. The cars are always at least pretending to drive. They ai is planning what it would do and comparing that with what the driver actually does. When there’s a big difference that is uploaded to Tesla for analysis. That’s how the ‘Tesla hive mind’ works. That analysed data then goes into a future software update. Great example is that is how Tesla’s learned what ducks are, and not to run over them. (Search YouTube... it’s amusing).
