The policy problem is that there is a large chunk of people who don't even think there is a problem. How is that going to be solved with a different "mix" of tech?
The different mix of tech will make it cheap/easy enough to do the "right thing" from a carbon perspective that few will do anything else.
I could burn my trash but my taxes pay the city to pay a company to come around once a week and collect a barrel from my house so why bother.
I drive ICE cars because in terms of results per dollar they're an obviously better deal than anything with lithium batteries. When it's no longer the economically obvious choice to drive ICE cars I'll stop doing it but not before then.

Note that this may happen with policy alone. Many countries and cities around the world are now heavily subsidizing electric cars, through things like tax breaks and waiving parking fees. This is only possible because electric cars are an available option.
How does people having the right opinion change anything? I live in an extremely liberal city, and I still see people driving almost everywhere. They’re not all driving Teslas or even Priuses either.
