I want to see what happens when one of those things breaks. There is absolutely no dispute that they will break in practice, but if they leave glass shards all over the place, they'll be entirely unviable. I'd also like to know if they will be able to with-stand super-high-load traffic, like the transporters used to carry big things like the space shuttle around.
