Anyone that's ever been fortunate enough to visit Hawaii knows how wonderful a place with such regulations is. Even in areas far less dense than Sao Paolo, I got a sense of relaxation from simply driving on the highway that I don't get (even in lovely rural stretches) when my attention is beggared away 10 times per minute by fast food signs. I doubt that society can yet fully quantify what we are trading away to make a few billboard operators wealthy and satisfying a few advertisers.
There are relatively few billboards where I live, sometimes none.
As soon as I cross some boundaries (city? county? not sure) there are TONS. And instead of ‘traditional’ billboards they are bright LED based ones that draw your attention and switch every 5-10s. It’s horrible.
