There will NOT be different sizes of the CT. C'mon kids... this idea is just ridiculous.
People are waiting 6 months to get a Model 3, and Tesla has been manufacturing them for almost 5 years.
The Cybertruck isn't even in production yet, has potentially a MILLION preorders, and someone is speculating that Tesla is going to make it in TWO DIFFERENT FORM FACTORS?!?!?!
They're struggling to even get one out the door in a single form factor (and it'll be MUCH more expensive than originally expected).
Unless by "smaller one" you're referring to the Cyberquad, this will never happen.
