Leaving your phone behind in daily life is less than trivial.

* My car insurance is currently only on my phone, and the printed cards in my glovebox are years out of date. I cannot drive.

* If your car has LTE or 5G you should not use it. Those will leak location data.

* It's almost moot if you do a transaction with a credit card. You need to use cash to not leak data. It would be a signal if you only take cash out of an ATM once in a blue moon. Many 'sensitive' transactions, such as medical care, can generate paper trails.

* In some cities it's moot due to the large number of cameras with facial recognition. In fact, to someone that has both phone data and city facial recognition data the fact that you don't have your phone could be used as a signal for closer investigation.

* If there is an emergency, such as you are arrested, or there is a medical emergency in which you need to go to the hospital, do you have a contact's phone number memorized?

Yes. 911.

Not sure if this is the norm elsewhere, but in Georgia police don't always ask for your insurance card anymore because they're able to lookup your insurance information when they run your tag.

I was used to this too and got pulled over in Utah and ticketed because Utah can’t do that, my insurance card is in an app not saved to my phone, and we were in a desert with no signal.

That Utah cop was a jerk. Now I have a pdf on my phone’s drive and a print out in the glovebox.

In the state I am in the police are able to lookup your insurance information, but it is still against regulation to drive without your insurance documentation.

AFAIK, Georgia still requires you to have a paper copy in the car even though cops can verify off the tag.
