"But two Democratic senators, Edward Markey of Massachusetts and Richard Blumenthal of Connecticut, have introduced a bill that would force the industry to seal off critical computers and add technology to stop hackers in real time."

Why do governments feel the need to dictate the little details? Instead of forcing all car manufacturers to secure cars in the exact same way how about just holding them liable for the consequences if a car is hacked? Car makers can then decide how best to secure the car which would lead to a more diverse and hopefully innovative security measures.
