It's a feature we like now that we have it, but not one we asked for.
Also: Hyundai/Kia cars have physical keys and are known to be trivially hot-wired. Given the "kia boyz" I'd have a hard time moving to physical keys again. Again, sorry!
Is mentioned vulnerability affecting older/cheaper cars? I don't need to press any buttons on my key fob to enter the car and turn on the engine.
