My prediction is that in fewer than 15 years, we will be debating whether human beings should be allowed to drive on highways.
After all, we are prone to road rage; rush headlong into traffic jams; break rules; get distracted; and crash into each other. That is why our automobiles need tank-like bumper bars and military-grade crumple zones. And it is why we need speed limits and traffic police.
