Aluminum is really easy to fatigue and fracture. In a car that is vibrating and jostling all the time, this could happen surprisingly quickly.

  Airplanes flying for decades are made of aluminum.

    Comparing car design and operating conditions to that of airplanes is kind of silly. The operating conditions of aircraft are far better defined and restricted. Additionally, aircraft airframes are regularly inspected and fully radiographed at certain intervals. Components that develop flaws are changed out when the flaws are detected. The same is not true of cars.

      Tesla isn't using aluminum "cables" either. They use the material for large rigid bus bars. https://news.ycombinator.com/item?id=35014013 https://news.ycombinator.com/item?id=35014013
