You might get up votes if you accompanied a controversial opinion with a reasoned argument. However, making only broad, unsubstantiated statements is a waste of bandwidth and everyone's time.

China is also the world leader in sustainable public transportation solutions

They're a "better than ICE cars" thing. I'll take whatever improvements I can get

Why not? This has been researched many times, and the results are consistently that it is a good thing already, and getting better, in regards to overall co2 produced

They're also far more efficient than fuel cell too

I assume you mean that they're not a positive for our environment, even so they're much better for our local environment, which is still one better than petrol and diesel cars imo.

When coupled with electric buses and high speed trains, they’re plenty fine. We’re not going to reach a level of infrastructure anytime soon where all travel can be accomplished through public infrastructure, even in China where they have ten times the public transport infrastructure of the US.

Electric cars by themselves aren’t a good thing, as in, the USian belief in “an electric car for every person” is insane and if they convince even half the world of it we’re going to destroy the other half mining minerals, but using electric cars to supplement sustainable infrastructure and support areas yet without access to public transit is a necessary step on the path towards sustainability.
