It all works out fine because of something called “human judgment.” But what company is going to program its driverless cars to break the law? And what regulators will approve that product, knowing that it has been programmed to break the law?
Not surprisingly, a survey by IEEE, a technical professional organization dedicated to advancing technology for humanity, of more than 200 experts in the field of autonomous vehicles found that of six possible roadblocks to the mass adoption of driverless vehicles, the three biggest obstacles are legal liability, policymakers and consumer acceptance. Cost, infrastructure and technology were seen as the least of the problems. "
