Elon clearly overpromises - but he also over delivers. SpaceX's current capability to deliver payloads to orbit is so far ahead of anyone else (particular considering they started from scratch only 20 years ago). Even their Starlink in just a few years had leapfrogged over incumbent providers. Tesla may not have achieved all they have promised but there is no denying they are the company that is leading innovation in not only EV but even in their approach to manufacturing.
