The thread about the Chinese high speed rail crash got me to remembering this video from a few years ago... Took me a bit of searching to re-find it, but thought it's pretty interesting, and got me to thinking... Especially the first bit about India and China...
(And yeah, the bit about Myspace dates it a bit, think it was from 2007)
(If you enjoyed that one, there are a few others, this is the one from 2009, but I didn't find it as interesting myself:)
