There wasn’t apparently a problem for this solution. And demagoguery had a great time instead.
Full-Hybrid cars do not need plugs. And they save a substantial amount on gas and emissions.
Plug-in full-hybrids neither need plugs. And they save a substantial amount on gas and emissions too. Yet they shine if you plug them.
So here you have a way to break the egg-and-chicken dilemma of infrastructure. First you legally enforce the exclusive sales of full-hybrid cars. Secondly you legally enforce the exclusive use of plug-in full-hybrids for fleet and company-owned cars. And infrastructure will develop of its very own market demand.
But it never happened. Perhaps the trail of money would tell why. Who would benefit of such course of action? Patent holders perhaps? For sure the health of us all. But our health is sometimes difficult to monetize. In the short term.
