All EV sellers here abide by that law. However, the "loopholes" you mention speak of remaining capacity, usually the batteries must retain 70 percent capacity after ten years or can be replaced under warranty. But if they fail, then they get replaced. What is nice, is that if they fall under 70 percent capacity then they can also get replaced. Early EVs were problematic, losing much of their capacity to retain a charge after a few years, which is why the law came into being.
“What is nice, is that if they fall under 70 percent capacity then they can also get replaced.”
Thanks, so they can lose close to 50% of their effective range (since most drivers know enough not run their EV down to empty). I think there were some other loopholes, like road hazards not being covered, etc.
