That’s only a small part of it. The bigger issue was that Hyundai/Kia removed like a 10 cent chip that would have prevented this issue on the US and a few other markets to save money.
Still, everyone puts the blame on Hyundai, and while they definitely deserve some blame in all this, let’s not forget the fact that people are still actively stealing these cars. These are still scumbag criminals doing this. An average person could see a car with its doors unlocked and the engine running and they won’t hop in and steal it, because they’re not asswipes.
