Tesla’s Semi prototypes do use 4 BLDC motors (well, more complicated than straight BLDC) from the Model 3. But I think optimization is really key for making it economically viable for mass cargo transport. Lazy copy-paste is great for prototypes and really shows how awesome electric is for making new vehicle configurations, but you really HAVE to optimize to be competitive at scale. Tesla has succeeded over the last 9 years against all comers BECAUSE they’ve optimized. Of course, manufacturability is one of the optimization constraints...
