I am from America and I can say with authority that Americans can't follow orders, have no common sense and they like to sue people for exposing their own stupidity.
My first proof is from my job where I work at a photo lab with a self service digital kiosks for people with digital cameras. Keyword "self service" which in America apparently stands for sit down and have some one else do it. Some lady, usually a boomer ( someone born after World War 2, engaged in group sex, cursed authority and smoke weed in the sixties and now doesn't want their kids to do the same thing) will come in and say they know nothing about computers (even though their generation started the information age) and I try to not roll my eyes and say that's why Hillary lost the nomination. Any way they will inevitable produce a digital camera that cost more than I make in a week, clumsily open the battery compartment and try to insert the battery into the computer ( I shit you not) which is when I point out that the small plastic thing next to the battery is the memory card. I then patiently explain to them, in a matter much like a parent trying to teach a child who has obviously fallen off one two many seesaws, that the name of the type of card it is is clearly printed on the device and will match what is clearly written on the kiosk. From there I proceed to show them how to use the kiosk while the device is speaking, I repeat speaking, directions in clear English along with written instruction and visual demonstrations forming on the display on how to print their photos. All this while they marvel at modern technology they way I imagine hillbillies did a hundred some odd years ago when electricity was introduced. That or the apes in 2001 when the obelisk appears and they figure out that it's easier to bash each others heads in if you use a a bone as a club. This only happens with American customer and can say that because I have helped German customers and all I have to do is set the machine to speak German (which freaks me out because it sound like a Nazi barking orders out at Auschwitz) walk away let them figure out the rest.
Case for point two and three is that all disposable coffee cups in America say "Caution, Contents May Be Hot"
because some old lady bought a cup of coffee at McDonalds, proceeded to dump it on her lap and sustain third degree burns on her lap, sue McDonalds, and then was awarded 100,000 US dollars because the jury believed that McDonalds was negligent in not warning their customers that coffee is hot and should not be poured on yourself.
The sad news as that may be, even worse is that this inspired other people to do the same thing in different ways such as a man who ordered a cup of coffee at the drive-thru, place said cup between his thighs, apparently because his cup holders were occupied with other tasks, inadvertently(imagine huge quotation marks) squeeze his thighs together so forcibly that the cup's contents sprayed up startling him so much he smashed down on the gas and slammed into the car in front of him. Last I heard he was suing McDonalds for ten million dollars.
