"Until the '60s, governments were not really involved in car design. Then people like Ralph Nader started noticing that a lot of people were being killed in cars and made it clear why this was happening. We have spent the last 35 years or so designing safety into cars, and it's had a pretty dramatic effect. . . We're in that same era now with security on computer systems. We know we have a problem and now we need to focus on design."
