I saw something about this recently, don't remember where, something I was reading on the internet. So I think they're also selling it in the US.

You might have to go back to Ikea for accessories, but where do you go where you need repairs on the brakes or automatic shifting? Also it's clearly not as easy to assemble as a dresser or bookcase, and there's potential for injury if you don't assemble it right. So I understand the concept behind it, but I have questions about the implementation.
