From what I’ve seen: EVs normally produce about half the carbon of regular cars, mostly from making the batteries. Switching fully to EVs would therefore reduce worldwide emissions by about 8%, compared to 16% by just getting rid of cars completely. EVs also don’t fix the societal problems of cars including sprawl and all of its related problems.
An ideal future would have no internal combustion engines and only EVs. But there would be a lot fewer of them, and preferably in a much smaller form factor.
As an unrelated side note, when I read ‘ICE’, the first thing that came to mind was the train. I’ve never even been to Germany…
