So I'm trying to figure out what the point of the "start car" option is in the Tesla App. I accidentally hit it once, and it asked to use FaceID to verify me, then started a 2 min timer to keep the car on. With a Model S/X I know you can use your phone to turn on the car/drive it if you forgot your fob. With the Model 3, the phone is the fob, so why is this option even here? Doesn't walking up to the car and trying to drive it with the phone in your pocket turn the car on automatically? Could I (in theory) allow someone else to drive my car by turning it on remotely through the app and without them having a key card or a paired phone? Would the car just turn off after 2 minutes??
