In case you didn’t know, Münecat recently uploaded a three-hour video debunking evolutionary psychology: https://youtu.be/31e0RcImReY
I figure the overlap between hbomberguy and münecat viewers in the Venn diagram is basically a circle, so that should help if you have an hbomberguy craving.
You don’t do that. You present the cop a QR code generated on the fly by the ID app when selecting “show ID” (or driver’s licence, in our country) that they then scan with their equivalent app or device. You don’t physically give them the phone. At least that’s the idea.
Like in many countries (traffic or street) cops here barely have a high school education and it’s not unusual for them to be too stupid to be able to scan a QR code. So carrying your plastic cards with you is prudent.
