You're not giving good counter points for the obvious benefits of CarKey. That's what I'm getting at.
I never said CarKey will be unhackable. I'm saying it's more secure than a keyfob. It's a definite plus.
By repeating the fob's signal, that someone could also start the car and drive. That's no good.
Funny you mentioned 5 hours. iPhone has a power reserve after the phone shuts off for up to 5 hours for NFC:

And it's weird you're accusing me of a ridiculous hypothetical scenario when you mention a scenario of being without a charger for 5 hours after waking up to a low iPhone battery. That scenario will never happen to me or a lot of people. I wake up, I have a charger at home, in my car, where I work, my coffee shop, gym treadmills have a usb port, etc... so what scenario would I be in where I will be without charge for 5 straight hours after waking up? And that's assuming I wake up to a 0% charge which has never happened in my life. I've woken up to 15% before which then I would turn on Low Battery mode and then get in my car to let it charge while I drive.
So no, I don't lose that point.
I already mentioned I forget my keyfob in my pants more than I've ever dropped a phone. I've had a keyfob broken due to leaving it in the washer (had left it in the washer a few times). Increased chance of dropping a phone is a ridiculous hypothetical situation you mentioned earlier.
Or telling me to not drop my phone when I use to unlock the car, right? Or do you want me to drop my phone to prove your point?
It's weird that you consider my points ridiculous, when you give ridiculous scenarios yourself.
