The (many) processors on modern cars are perfectly capable of handling a cryptographic handshake to make a completely local decision about unlocking. Between the touchscreen and processors, they are perfectly capable of letting the owner do the key management. There is no reason they can't interact with a smart phone over bluetooth to unlock.
Instead, the idiot manufacturers tie it all to the mothership where a single vulnerability can affect thousands of people all at once.
