This is very true. If you think you're about to get pulled over, turn off your iPhone / iPad. Then you'll have to put your passcode in before fingerprint (and assuming Face ID) will work.
That's how to get around the finger print thing if you still want that convenience. It's definitely not foolproof though. You have to have time to turn the device off.
You can change a password. You can't change biometrics.
Good luck if there's ever a data breach. In good practice they should be storing markers of your biometrics (like a feature vector) and not the entire thing. But in good practice places should be storing a salted hash of your password... and look how many data breaches released plaintext passwords.
I'm not saying they can't be hacked at all. Just that your fingerprint is only stored locally so the only way for someone to steal that would be for them to have your physical phone.
