its not really 15k though, even countries that are near China and has a BYD factory built in it doesnt get that pricing. The Dolphin in Thailand is a 700k Baht (~19k USD) vehicle
unless china could both skirt laws, ontop of have a supply chain that already exists in the Americas thats is equal or cheaper than in asia, they would not get that pricing unless they stripped the already stripped down vehicles even further.
