> anyone with the credentials can find the car, unlock it, get in and drive it away

While the first three are true, you can't actually drive the car without an authorized key. Adding a new authorized key requires an existing authorized key. However, if you have a Model 3 and keep a valet key card in your car, then yeah anyone who can unlock your car can also drive it.

You can definitely drive my Model S with only the credentials. I have been in a situation where I had to install the app on a new phone then unlock it and drive away. Model 3 may be different but I don't think it is.

I don't think that's true? You can enable keyless driving with just a Tesla account credentials.

You still need some sort of authentication before the vehicle will let you switch into drive. In a Model 3, those options are either an authenticated smartphone, a key card, or a key fob. You cannot enroll any of those three keys without having an authenticated key present.

I do not believe this is true. You can start the car with just the account credentials. You will have two minutes to start driving, as the GP states; it’s called keyless driving mode. I’m pretty sure as I have used it when my phone broke and started the car with unpaired iPad. You need a key fob or key card to add a new paired key/phone, a paired smartphone doesn't work for that.
