New high-end cars are among the most sophisticated machines on the planet, containing 100 million or more lines of code. Compare that with about 60 million lines of code in all of Facebook or 50 million in the Large Hadron Collider.
The sophistication of new cars brings numerous benefits — forward-collision warning systems and automatic emergency braking that keep drivers safer are just two examples. But with new technology comes new risks — and new opportunities for malevolence. Cars have become “sealed-hood entities with complicated computers and modules,” [nytimes.com] said Eben Moglen, a Columbia University law professor and technologist. “All of this is deeply nontransparent. And all of this is grounds for cheating of all sorts.”
