You're talking about Via
You're talking about Via Motors - a company that just recently unveiled their trucks, and which hasn't entered full production/sales as of yet. Via's launch did include PG&E as a design partner and customer. Via's products are geared more towards construction/utility users than it is to the general public. It's way too early in Via's history to say "no one is buying [their] hybrid trucks" .. give them a few months of history before you leap to such a broad conclusion.
