I am witness to the fact that Tesla's have a deficient breaking system as it is reliant on electricity if you're ever out of power your brakes won't work because they do not have hydraulic assist or something like that they should be hydraulically actuated not electrically actuated from a mechanical function to actually engage when there is no power so be aware all Tesla owners keep your batteries charged it is a life or death situation I've seen the Tesla truck lose its brakes on a mountain for Wheeling and it almost tipped over so drive wise and keep them batteries charged or don't buy a Tesla altogether keep it safe
