  • EV batteries are actually significantly different than the batteries in your laptop or phone, and are designed to have minimal degradation over many many years of use. The coolant loops also help to moderate the temperature between cells, which eliminates problems of hot spots and the heat stress that a phone battery will experience.

    For instance, my car has over 300 battery cells in it, which results in say a 100 MI Drive will only use each cell draining by about 1/3. The much lower cyclic rate on these cells results in a much longer lifespan, and the battery conditioning using liquid coolant is how they achieve that.










  • A couple of my criticisms with the article, which is about “autopilot” and not fsd:

    -conflating autopilot and dad numbers, they are not interoperable systems. They are separate code bases with different functionality.

    -the definition of “autopilot” seems to have been lifted from the aviation industry. The term is used to describe a system that controls the vector of a vehicle, is the speed and direction. That’s all. This does seem like a correct description for what the autopilot system does. While “FSD” does seem like it does not live up to expectations, not being a true level 5 driving system.

    Merriam Webster defines autopilot thusly:

    “A device for automatically steering ships, aircraft, and spacecraft also : the automatic control provided by such a device”
