If someone could invent so-called "binary load lifters," the future would be NOW.
You're wrong. They avoid the "existing train route" because it only exists in your imagination.
From the site "When you print on a color laser printer, it's likely that you are also printing a pattern of invisible yellow dots. These marks exist to allow the printer companies and governments to track and identify you — presumably as a way to combat money counterfeiting. When one person asked his printer manufacturer about turning off the tracking dots, Secret Service agents showed up at his door several days later."
