But he also said the configurator would probably open in 3 months. 5 more days and if it doesn't happen and we can add it too to the growing list of 'things Elon has been too optimistic about'.
Yep, that's exactly what is so amazing to me. How much Tesla gets away with in missed promises, misleiding presentations and other shady shenigans without any material impact on the stock price. I certainly gained from it too but each time I am wondering, will the ride keep riding or should I get out because it will catch up with them?
I'm with @Krugerrand - I think your definition of "probably" is "probably" closer to "a promise" than my understanding of the word.
Timelines in software development, construction, court case resolutions, designing and building something the world has never seen... they are highly unpredictable. @Johan nailed it IMHO - Elon is highly optimistic, and uses that to drive goals. I find his candour and honesty quite refreshing - he answers tough questions as he sees and there's no scripted lawyer or handler pulling his strings. Maybe they try to yell at him after, I don't know. But after watching countless videos of him, and seeing results, and including the various delays and changed deadlines etc, I truly believe he's an honest, driven guy. What he, his management team, and his worldwide staff are doing is (understatement of the century) not easy.
@bsd mentioned the Good/Fast/Cheap triangle, as we know the "Fast" part of that is only in both of Tesla's cars' performance. But I'd rather have Good than the alternative.
"Shady"... well, just no. Except for two web pages: Autopilot, and purchase price (including incentives and gas savings). Those two I'm not happy about. And they seem to me to be opposite of all the other ways that Tesla behaves. It's a conundrum.
