I'm glad you have had a good personal experience with your Toyota's, I'm not convinced that means Tesla is proven however. Did you google "tesla problems"? If you did you'd view many issues that have cropped up which certainly make a good case for "unproven"; now you compare and contrast that with the good reports and make a judgement. For you the jury has come back with a glowing "all clear" - I'd counter that the tipping point for "proven" has not been reached yet with Tesla for many. Look at the previous discussions about the "next" thing in power/fuel right here in this thread.
