If you read the article, the order is "expected to be fulfilled" around 2020, and "it will be contingent on diverse conditions, not the least of which actually building the technology for autonomous driving".
Haha. So they placed an order for 100,000 cars, 4 years before they expect it to be fulfilled, and before the product they're ordering even exists?
Strange. They might be upset if Tesla has their autonomous car to market first.
(Not sure who will be first though. Mercedes is no slouch in that arena).
