It kinda is though. Snow deposition is a function of surface temperature, which is uniform across the sensor. Hit the wrong initial temp when you enter a blizzard, and deposition takes your vision in seconds. It can be hard enough to see out the windshield which has heating, wipers and anti-freeze wiper fluid fighting for it.

Do you realize how far you have moved the goalposts during this conversation? You started out with the suggestion that they "fully disable autonomy in September and enable it again in late April" and now you are talking about situations with "the wrong initial temp when you enter a blizzard". I will simply refer back to my initial comment in this thread: "there is going to be a decent amount of time between when a self driving car can handle most scenarios and when it can handle all possible scenarios". Blizzards are not in the "most scenarios" group. Barring emergencies, no one should be driving in a blizzard let alone an autonomous car.

  I don't think OP has moved the goalposts at all. LIDAR can work in snow but cameras get covered. And yes you are right, there will be a decent time between testing in some basic scenarios and testing in all scenarios. But I do not understand why Mr. Musk is trying to reinvent the wheel and rely only on vision when LIDAR has already shown that it works better. https://www.cambridge.org/core/journals/journal-of-glaciology/article/lidar-measurement-of-snow-depth-a-review/4419DF5C778946103080CB6187D434C0/core-reader https://www.cambridge.org/core/journals/journal-of-glaciolog...

    > But I do not understand why Mr. Musk is trying to reinvent the wheel and rely only on vision when LIDAR has already shown that it works better. Because he's sold a bunch of cars (and a bunch of stock in the company selling the cars) without LIDAR with the explicit claim they are hardware-ready for full self-driving.
