Put together a amalgam self-driving Sanisette [1] and you implement an even more ridiculous aspect of Idiocracy than its La-Z-Boy with a built-in toilet [2]. And while I make a joke about it now, someones in the future are going to convince a line of VCs to incrementally enable people eventually gaming/Facebooking in VR while hurtling down the freeway doing Number Two, and get handsome exits on each step towards that, and it will all be counted as a net economic benefit in the end. I'm either kidding, or will have checked out well before that ever becomes mainstream.
