I think we had this discussion when I first posted it about 7 or 8 years ago. Also, those examples I posted are very common in US films / programmes.
The thing is that Americans can see at a glance that it is bullshit. But for those of us who have no idea what could or could not be true, it is difficult to decide.
America (or Hollywood in particular) decides to show (for example) Clint Eastwood driving along in town and pulling up outside a building, no other cars parked there, he gets out of the car, goes in the building. No locking of the car, no apparent parking restrictions etc etc. It indicates that downtown parking is really easy and so safe there is no need to lock the car.
JR did the same in Dallas.
My question is - why does Hollywood give this (allegedly) false image when many people around the globe could think it is true? Note I'm only talking about the day-to-day things here, not the super special effects and all that nonesense.
Here's another - American soldiers always sing when jogging along.
