The phone that opened the car????
Really?
So you can't leave home without a smart phone?
Most people will use the car's app on their phone - if you have the phone on you and you're next to the car, the car will unlock. But there's also a card if you don't have a mobile phone and there's a fob too. I imagine most people buying a Tesla (or any other EV) would not leave home without a phone on them.
I leave home with only my phone these days - no cash, no car keys, no credit cards.
