Good post/reply. I shortened it just to reply to this one part.
"Predictions" mean nothing more than speculation. Sometimes right, sometimes wrong, it depends on the forecaster that you want to believe. I guess that is why the stock is priced FIFTY times earnings though many people took a bath when it was selling at ONE HUNDRED times earnings. All I am saying is speculation is just that, remember when Tesla was going to come out with a truck a few years back? That wasnt speculation and it's still not here.
Im a non believer. Tesla filled a void in the marketplace. No different than a clothing line, or Electronic product in an industry already well established. They have nothing special to offer other than the fact of having a different "engine"
Every legacy car company in the world is now starting production of that same exact product with an expertise in knowing what turns a buyer on regarding look and utility with a VASTLY larger showroom, service and distribution network than Tesla.
I personally think a bit extreme that Tesla will get buried to the status of something like the VW Beetle and I see nothing wrong with that but Tesla has proven it is not easy for them to innovate and change vehicle styles fast enough (at least at this point) to compete with the majority of the big companies and the styling tastes of the public. Add to that they only offer EV models and the legacy companies produce both ICE and EV. Consumers like choices.
BTW I do like Elon Musk and the industries he starts but as with Pay Pal and I wonder at times with Tesla is his intelligence and visions able to execute to the fullest extent possible? I may not even be typing this way if now or even years ago he provided more models that the public desires = Trucks and SUVs.
Time will tell.
You forgot about the worlds largest dedicated charging network and only network with bidirectional communication to the vehicles themselves.
