For as long as I live I’ll never understand how people could see that unveiling where the doofuses on stage hurl a big metal ball at the “bulletproof” glass and watch it crack during the live demo, and still think “Yeah I’ll pre-order one of those”.

Bulletproof glass is actually illegal by US safety standards. In fact, the side windows have to be easy to break by EMTs for emergency extraction.

Musk's engineers knew this, but were too afraid to tell him before the demo.
