Video also talks about limited vision of front cameras (blind spots and the major one pointed out is in front of the car). As a solution, the car will most likely remember what it sees as it drives forward and it also sees while parked with sentry mode (so it can see anything that moves into that blind space). I can see a few corner cases (i.e. low battery and disabled sentry mode and you approached the car from behind) and maybe they'll have contingencies for things like that where it warns you prior to driving forward in those instances.Munro & Associates published fresh analysis on the ultrasonic sensor system removal.
Their calculation of the estimated direct hardware cost was $114, making @mongo 's guess last week the closest. This was not including other costs though, including installation labor, supply chain management, inventory, floor space, poor quality, etc. I changed my model from the $500 previous estimate last week to $200. This $300 per car difference makes a $0.20 earnings per share difference for my 2023 estimates.
I hope Tesla talks about the BOM and all up cost/throughput savings per vehicle in Q3 earnings as I think the cost is much higher (the harness used to be closer to $50 x2 and ECU was closer to ~$32 and yes, they have economies of scale vs 2015 prices that I was privy to, but can't imagine it is that low now).
Also, I wonder how close Tesla is to removing all CANbus dependent components? This would remove all legacy wiring and unlock more materially large savings per car. The big one left being body controls.
