The main problem here is that manufacturers aren't incentivized to make great security systems for their cars. There isn't a ton of press about cars getting stolen like there is about data privacy. Imagine if the folks who built FaceID, TouchID, and Secure Enclave were tasked with building car security. Cars are a lot more expensive than phones and laptops, it would be worth the $50 or $100 in extra hardware to secure them. And as an added bonus, you wouldn't even need a key anymore because you could start your car with your face. :)
