I was wondering whether anyone technical out there knew the answer to this. How easy is it to relay hack the Model 3 given that the card works at such low proximity and the app is connected via Bluetooth? I will be adding Pin to drive when it arrives but it’ll be interesting to know. Also, from people who already have delivery, if the car is on the drive and your phone on the window sill — is the car unlocked? Don’t want to disable Bluetooth every time I get home. edit: window sill as it’s the closest point in the house to the car.
