Has biometric been considered for cars? I mean it’s used for phones and computers, why no cars. Maybe in addition to a key/fob. If it senses the fox and your biometrics (either finger or face or both even) it will start the car. If the car doesn’t recognize your biometrics, then you need to enter the key in the vehicle to start it. If it recognizes you can start it.
I have never had a phone that has successfully unlocked the first time using biometrics. I wouldn't say it is a solved problem or a solution. There are also implications with law enforcement when using biometrics. They can't force you to unlock something with a password, but they can forcefully unlock something with your fingerprint.
The older fingerprint readers that were on the back or below the screen worked perfectly and near-instantly (I've used several Nexus, Pixel and Moto phones).
At least some of the newer in-screen readers are slow and unreliable. I've heard that the ultrasonic ones are better.
The 5th Amendment is a nonissue here. If they have a warrant for your phone and you don't give up the password it is hard to get in. If they have a warrant for your car and you don't open it for them they will just smash a window. I doubt our cars are bothering to encrypt any of the ridiculous amounts of telemetry they collect.
