The first are those that believe that EVs are the future and love the cars Tesla is producing.
The other are robotaxi/FSD evangelists and believe Tesla will usher in the age of autonomous cars sooner rather than later. These people genuinely believe we'll have fully road legal autonomous cars (as in, requiring zero human input) by 2025 and that human driven cars will be outright banned in many developed countries by 2035 or even 2030. Some of them actually want Tesla to stop selling cars to the public in favor of stocking them for the robotaxi fleet which they are absolutely sure will be widely deployed in a matter of a few years.
