One cultural thing I noticed after leaving the USA is the obsession among law enforcement and the private sector for asking for ID all the damn time, seriously it is crazy how common it is in the USA. I used to get quite a kick out of saying I don’t carry ID, which can be dangerous and lead to arrest. Being a pedestrian in the USA is begging for a cop to pull over and ask you for ID, a lot of police incorrectly believe it is illegal not to have and carry ID(I have been told that by police point blank).
Cops in the USA are almost comical in their ID requests, they will literally ask random people on the street not suspected or accused of any crime for ID. If you call the police to report anything the officer will ask for your ID when they come out, if you have some guests over they will ask everyone for it. If they pull over a car for speeding they ask all passengers for ID. ID ID ID ID ID ID.
In the USA you are asked for ID in retail stores for buying random things, Walmart for example there are about a million items they sell that trigger the ID request. Weed killer, batteries, tools, knife sets, the list is enormous and most cashiers ignore it. Stores ask you to produce ID for legally age restricted items no matter how old you are, an 80 year old gets carded. I had a ton of hassles using a US passport as my ID, even being told only state ID is valid(the USA is not a state you heard it here!).
You cannot buy a domestic bus ticket or airline ticket without showing ID, for what possible reason?
All this ID showing solves nothing, the only place it makes even a speck of sense is legally age restricted items and then only for those could conceivably be underage.
