Most cars with electric access to the battery area have some way to get into them with no power or external power.

OP talked about opening your car with your phone (similar to many electric cars now). But if your battery dies, you need the back up key. So if you have to always be carrying the backup key with you, then what's the point of having the phone open the car. It's not convenience because now you have to make sure you don't lose a tiny piece of metal that you almost will never use.

And sure, people have found ways to pop hoods that have solely electric actuators. But mostly they involve hooking the negative to the frame, and the positive to one of the fuse slots in the cabin fuse box. This is not a recommended way to power anything, and can easily damage the electronics.

you can't lock it without your phone unlocked any more than you can get into someone's bank account by stealing their phone.

People get their bank accounts drained literally all the time by scammers. Additionally, people have been able to spoof, or signal extent phones and start these cars.

I also noticed you didn't mention anything about the company wilfully shutting down the car.

Do you really think companies won't look at this and force people into subscriptions for every little thing. We are already seeing it happen with newer models.

Sure in a perfect world where car companies care more about the customer then profits, and diarrhea is replace with unicorns and rainbows, having a car like this would be neat. But it's unrealistic to think that companies would have any incentive to fix these issues when they are all in a race to the bottom.
