Yes I agree its hard to comprehend. But I guess in all the big global cities people all live in high rise apartments?I had no idea that elevators move that many people each day. Kind of finding that tough to understand.

I would be curious of that metric. Rural China and India use a lot of elevators? Just a question... The devil is usually in the details...I was surprised as well.
The elevator moves around 2.7 billion people per day, or about 1/3 of the world's population each day.
Prior elevators were mostly used for goods until Elisha Graves Otis showed, at the NYC World's Fair, that the elevator brake he invented provided a safe way of stopping it from plummeting.
the least safe, though.Bike. 98% efficient.
