Once all cars are electric is global warming no longer an issue? What is the main benefit of electric?
Even if there was no efficiency gain, electric cars move pollution out of city streets and into less densely populated areas.
If electricity is produced using less polluting methods like hydroelectric plants, then there's net benefit.
I don't see how thousands of small scale filters that may or may not be maintained (ie. in some countries people cut DPF out) are better than one big efficient properly maintained industrial filter.
Also decoupling power generation from consumption allows for making overall car energy usage greener over time. Not possible with ICE. [1] https://www.bloomberg.com/news/articles/2019-01-15/electric-...
This article says that electric cars actually produce more CO2 emissions. Hard to know what the truth is when sources are conflicting.
A conservative and logical estimate is that Electric Cars emit more CO2 gas overall because it requires an extra conversion step.
Gasoline automobiles: Source --> Kinetic Energy
Electric automobiles: Source ---> Battery Power --> Kinetic Energy
Of course the real answer could be far more complicated since even gasoline distribution causes energy usage itself. The controversy and hardness to find a definitive answer makes it reasonable for me estimate that electric cars don't really do any obvious net change in energy efficiency OR green house gas reduction At All.
It doesn't match the hype.
Yes, with current energy mix electric cars in some places might be emitting slightly more CO2.
Just for US data report quotes electric fleet averages on 54MPG - average MPG of new ICE is 25MPG.

Logical is to compare ICE vs electric drivetrain efficiency and https://en.wikipedia.org/wiki/Carnot_cycle.
Even with dirtiest energy generation electric cars are not worse than normal cars of similar size.
Also the conclusion of my response is that electric cars don't make any reasonable change to energy efficiency or green house gas emissions, which your response fails to contradict.
Is this not reasonable?

I'm not a biased person if you clarify the implications of your "us data" and it's sources I can completely reverse my opinion in an inhumanly unbiased way.
