They don't, the cars come with (RFID?) key cards that work without a server. These people had left their key cards at home and relied on their phones probably just so they could have thinner wallets. Which is pretty stupid, it means you can't even unlock your car in a basement parking garage with no signal to the car...

Non-tech people don't know that a phone might not work to unlock a car in and underground garage. Tech people would assume Tesla built this thing to work without network availability. Maybe via Bluetooth with some key exchanges? This assumption by coder and companies that services are always available is a nightmare. How many sites completely stopped working last time Facebook login went down? I am not saying build for every possible situation but don't assume the service you are relying on is always available.

It's not stupid. The app could easily unlock the car using Bluetooth. Why does it need a server?
