The level of engineering required to create and maintain this stuff must be crazy. It's actually amazing what the human brain can think of and create.Yes I've actually seen something like the Bagger in Germany as a teen. Pretty crazy but it's so big that you don't really think of it as a vehicle. More like a structure similar to a factory.I actually see the Bagger quite regularly as the coal mines are near a highway close to my home in Germany and I've had two tours around the coal mines and can't overstate how absolutely tiny you feel driving below it with a bus.
