Cybertruck isn't nerdy, cyber-anything always sounds wrong to me.

Do nerds call the web cyperspace?

When anybody calls anything cyber-whatever it used to be a red flag that they were probably clueless. Unfortunately cyber security has become a de facto term in industrial control networks.

Only seen it used in a useful way when discussing legal matters.

That said, at least around here military seems to have adopted it which might give the name a boost with parts of the truck buying demographic?
