This was not fixing a safety related defect, not recognizing all stationary objects is a clear software limitation included in the owners manual. This why the driver is fully responsible for watching the road. It's like blaming a manufacturer for a car on cruise control hitting a stopped emergency vehicle.
No. It’s like blaming a manufacturer for a car on lane assist veering out of the lane and crashing when the road is straight.
Even if Tesla says “driver needs to be attentive”, autopilots published capabilities should handle these sort of situations, so Tesla could have liability in case of a defect. Also, if Tesla discovers a defect and updates the software to remedy, that is great, but they should not be absolved of notifying customers and regulators of the defect and how it was fixed. They shouldn’t be able to “cover their tracks” with a software update.
