Earlier quoted context omitted.
Fire Musk and the board could also risk a situation similar to Apple's board firing Steve Jobs. Musk is taking too many chances with too many things, often unnecessarily, but without him Tesla could be trampled by the big carmakers in the coming years in the EV market. Who at Tesla will still want to add rocket alloy to their cars to make them the safest ever cars? Chances are whatever new CEO they hire will see that…
The big car makers will be flooding the EV market, irrelevant of Musk presence.
If toyota decides they can make a yaris or aygo as a purely electric vehicle, tesla will be nearly unable to catch that large, low end market segment.
Also, you need low-end, mass volume cars to be able to push eletric infrastructure and replace the current gas infrastructure. (although i think using hydrogen and reusing the gas infrastructure might even be a better solution personally).
