I have driven/travelled across a lot, nearly all, European countries and the other one - the UK.
You do not get those huge screens on stilts anywhere that I have seen in Europe, that seem to be common across the US.
To be fair, I've only driven across about 10 US states. However, I do have Holywood's and other's output to act as a proxy and it seems that US companies do love to shout it from the hill tops at vast expense and fuck up the scenery with those bill board thingies.
Try driving around La Toscana and say Florida. I've done both, multiple times and I'm a proper outsider. I love both regions quite passionately but for very different reasons. FL has way more issues in my opinion but we are discussing bill boards so let's stay on task.
Billboards require power as well as the obvious physical attributes. They are an absolute eyesore and in my opinion should be abolished. Turn them into wind turbines and do some good - the basics are in place.
However. I know FL quite well. It has a lovely climate (unless it is trying to kill you). Florida man almost certainly invented air conditioning and FL man being FL man took it to the max when confronted with a rather lovely climate.
FL man is a thing and it turns out that CA Pres. can be weirder than anything seen before.
US - remember your mates, we remember you as is and don't hold you accountable for going a bit odder than usual for a while.
