You base this off of part of a twenty minute Youtube video. I have no interest in self driving cars personally, so I can't say I follow where the US is in this regard.
They're driving a $30,000 car and it navigates around scooters and pedestrians with ease.
Aren't there self driving taxis in cities in the US? If they're killing pedestrians and people on scooters, I would assume that it would make the news. If they're killing people in China, it's less likely that we'd hear about it.
The traffic signals broadcast their status and countdown the seconds in real time on the vehicle display.
Not gonna lie, that is really cool. But that doesn't require self driving nor EV. I'd love to see that implemented in the US.
Skip ahead to the trade show and you'll see batteries taken out of service that ran for 800,000km and they're still at 80% life.
This is a trade show. I've worked in several industries and attended trade shows. Over half of what is shown at a trade show never happens. Much of what does make it to the public is not as cheap or as good as what was promised. Many things are just complete fantasy. I bought a Cadillac in the early 1980's that I finally got rid of after 360K miles. I could have kept driving it, but the AC stopped working at the same time it developed a leak in the sunroof and some other minor issues. There are Toyota's that have hit one million miles. Those aren't the norm though. I suspect those batteries aren't either, if they are real at all.
Check out the polymer batteries without a liquid electrolyte. They have a working sodium battery sitting at -50c and charging just fine.
I find it amusing that people who doubt everything and anything that is said by the US government or US companies will believe anything said by their Chinese counterparts. I've worked in China and find there are a lot of parallels between the US in the 1950's and modern day China. Perception in China is a lot more important than reality in many cases.
Oh and if you still think this is all a joke watch the safety testing at the end.
I have friends in Russia, Australia, and other places that import Chinese cars. I've heard the same thing from most of them. Getting parts when something breaks is nigh impossible. Chinese car manufacturers refresh car models every 2ish years. Getting parts becomes impossible because they make a limited number of replacement parts even when a model is still in production, Once it's run comes to an end any parts that don't get carried over to the new model are no longer produced. That 800km battery is pointless if a steering wheel position sensor goes bad and the car won't move and there are no replacement parts available.
The reality is that China was really smart to jump on EV manufacturing. They saw that US, EU, Japanese, and Korean car manufacturers were too far ahead when it came to ICE engines. It made little sense to try to catch up on those as they had a 100 year heard start. Obviously environmental concerns also made EV's a smarter bet as well. Unfortunately having a car that has a better than zero percent chance of becoming disposable once it hits the 3 year mark isn't so good. Suddenly buying a $60k car that will last for ten years becomes a safer bet than a car that's half the price but may need to be replaced 2 or 3 times in that same period.
