The semi is quite interesting. The presentation was a bit underwhelming, Elon was very nervous and the stuttering wasn't something I expected. To me this shows how great Steve Jobs was salesman, when he did his presentations.
Tim Urban has a great essay about different levels of prep people do for talks [1] which he wrote when preparing to give a Ted talk. Musk's talks are on the "Wing it" side of prep while a Ted talk is suppose to be on the "Follow an exact script - Happy-Birthday-Level memorized" level.

Tesla has a price-to-sale ration of nearly 6, while Nissan and GM are <0.5. So Tesla is mostly image and vision, not reality. Therefore it depends on Musks presentations with visions of a glorious future.
Sometimes you gotta get people to believe in a better reality :P
"[...] as long as 1) wealthy consumers in western
nations but also China are eager to seek indulgence
by way of green-washing and, 2) are in search of a
Steve Jobs replacement persona onto which they can
project their hopes for a gleaming future and,
3) are disillusioned with the establishment and
its leaders, the company will likely succeed to
raise cash again."
"Getting the Model 3 up to a production rate of 5,000 a week is what will start to prove out Tesla's current stock price, not a slick demo."
Yes, currently it looks like this is out of reach of Tesla.
The stock price is not the arbiter of whether a company is vision or reality. Nothing would change about those companies if public opinion suddenly shifted and made those ratios go the other way.
