I'm not in the market for a BYD but I'm stoked to see Telsa taking a beating.
- This is why they’re outlawed in the US. Tesla can’t compete.
  
  tHe mArKeT WiLl ReGuLaTe ItSeLf!
- TBH nobody can compete with BYD at this point at normal consumer level.
  
  It's crazy how big BYD is in China friendly countries (I'm in SEA and their everywhere) though Japanese cars are still hard to uproot from many cultures and I hope Japan comes up with an affordable EV soon. I'm not driving Chinese spyware, especially in the current political climate.

I just came back from Thailand. I got a Grab and driver pulls up in a BYD. I have never been in one. It is a really nice car from what I can see. I asked dude how much the car was. He said it was under ฿1M Which is $30,000 US. I was shocked.
I saw hybrids and electric cars everywhere there.
- Meanwhile, the US market keeps pumping out oversized, overpriced EVs all while the manufacturers complain about lukewarm consumer demand.
  
  If they love Rand so much, let the market decide. Fucking cowards.
  
  Same in the EU, though its changing slowly. The French started a Trend with affordable, smaller EVs.
- They are outlawed in the US. As to why we don’t see them. They have fully robotic fabrication at their facilities. No humans involved.
  
  Land of the free ^{for the rich}.

  That's what heavily state subsidised and controlled manufacturing will get you. Not saying it's bad, but it is just the reason they're so cheap compared to many other brands that are not subsidised as heavily from their government.
  
  Are there many country governments that don't subsidize their transportation industry?

  I heard about the heavy state subsidies from someone living there. Sounds good to me.
  What does controlled manufacturing mean?

That puts it at a 12C charge rate. The question is how the batteries will hold up over time. Does each fast charge cycle make a noticable degradation to the capacity?
If they're using LFP it's probably okay, they can usually take higher charge and discharge rates at the cost of lower energy density. But I'd be worried if they're pushing NMC battery chemistries to 12C, as I think that'd kill the life of the battery.
- Pretty sure BYD uses LFP. There's little reason to use NMC unless you're trying to reach the absolute maximum possible range. I think that's only really an important factor in North America.
- Genuinely, even if the degradation ws ateocious I would only care in so far as its environmental impact. Long journeys in EVs suck but getting charge time down is the answer...unless hydrogen takes off
  
  Yeah, I'd only do the quick charge a few times per year, I'd trickle charge all night the rest of the year.

Why when we can have lead-gasoline nazicars?
