I can't wait to get a ticket for driving without a license because my phone ran out of power.
For instance in CA, CVC12951 makes it an infraction to drive without your license in your possession, and a misdemeanor to not provide it upon request by a LEO
They look your license up anyway when they get to their car to validate it isn't revoked.
I would much rather provide a physical license than hand my unlocked phone to law enforcement.
