Those two things are unrelated. The ball joint lets you position the wheels (ie steer). I would be monumentally shocked if Tesla didn't put rubber seals on the ball joints.

  You can judge for yourself[1] whether the joints are sealed with rubber or not; it appears to me that they are. [1] https://www.youtube.com/watch?v=DgdKZMlzQog https://www.youtube.com/watch?v=DgdKZMlzQog

  Thanks. I don't know why I misread that.

Of course Teslas have spill-brakes (brakes that convert kinetic energy into heat and then spill it into the atmosphere). Regenerative braking is great, but safety still requires disc brakes. And Mr. Musk will sell you red ones for a couple of kilobucks. http://shop.teslamotors.com/products/performance-red-calipers-set http://shop.teslamotors.com/products/performance-red-caliper...
