Technology

Efficiency of processes is different in every situation, including long-standing ones, like one area having plenty of seawater and some other area having just lots of sand, some places being moderate-temperatured and some like central Siberia with hot summers and cold winters, things like that.

Meaning that one can't say that gas cars are "better for the planet" or "worse for the planet" than EVs. Period.

This study is true for some set of conditions, but it's pretty clear that people referring to it will use it outside of the scope.

There are better arguments than unprovable claims. Say, EVs use "universalized" energy, that is, can be charged from the grid, while gas cars require different kinds of gas depending on the specific engine and regulatory requirements. EVs have electric machines in them, pretty similar to those in electric trains or whatever else, but that's not as important as less wear and more universality. EVs in theory should require less maintenance, but since these are usually new fancy cool things, their electronic components might have the common downsides of all new cars. Fire hazards are different between them. On the other side, gasoline can be stored more easily.

I mean, one would think civilization can exist without choosing just one.
