Earlier quoted context omitted.
Tesla sales are collapsing globally partly due to Musk's mental breakdown and are not likely to recover much, especially since Tesla no longer really has a CEO.
To me it seems to have very little to do with his antics. Surely inflation, market saturation, and increased competition is more probable?
For your hypothesis to make sense, first you would have to establish that Musk's antics have no negative impact on Musk's public opinion or public image.
In the meantime, you've started to see a global wave of both Tesla stores and Tesla cars being vandalized in protest over Musk's public support for Nazism. In some cases such as Germany you even had public protests against the neonazi party that Musk supports and promotes.
So you establish the fact that throughout the world people started protesting Musk due to his public actions. Do you think this change in public sentiment brings with it a neutral impact on sales?
