Prepare to be underwhelmed by 2021's autonomous cars

BMW, Ford, and Uber have all recently said they plan to have "fully autonomous" cars ready to drive themselves on the road in 2021 (see "2021 May Be the Year of the Fully Autonomous Car"). Ford says its fleet of vehicles will lack steering wheels and offer a robotic taxi service. But don't expect to toss out your driver's license in 2021. Five years isn't long enough to create vehicles good enough at driving to roam extensively without human input, say researchers working on autonomous cars. They predict that Ford and others will meet their targets by creating small fleets of vehicles limited to small, controlled areas.
