I was flying with a friend one time and he jokingly said "never hack the plane your flying on", while it was just joke, it's something I'd never actually considered although it's blatantly obvious. Sometimes people get caught up in their own curiosity, don't think through their plan and loose perspective on the consequences of their actions. While what they did was reckless and irresponsible, I think their overall intentions were to inform of the risk associated with vulnerabilities/hacking of this nature and raise awareness. I would assume that they have learned from this, and won't be shutting down cars on a highway to show off anymore. The thing about risk is that it's best dealt with when there is a clear understanding of it, the conversation on what is appropriate testing, and raising the general awareness of the public regarding these vulnerabilities are both factors that will hopefully mitigate risks moving forward.
