Hackers can steal your money. You may be able to get reimbursed, depending on how they did it. The novel thing about this Jeep story is precisely the fact that hackers are demonstrating an ability to do something worse than stealing money.
The cops can wreck your house, break your stuff, take your money, shoot your dog, deprive you of your liberty, and - if they think they can get away with describing you as a threat - shoot you dead. Even if you spend the time and money it would take to prove in court that all of this activity was illegal and unjustified, most of the time you'll fail, and even if you succeed you'll never get anything back.
I don't trust hackers or cops, but I can sure as hell see which one is the bigger threat.
It's not really novel because hackers are having a physical presence, it's novel because hackers are attacking cars. Even then, it's novel because hackers are remotely controlling cars. They've been able to unlock your car and drive away with nothing but their Android phone for years.
Meanwhile hackers can break into the control systems for the power grid and shut down electricity, causing major damage. They can open or close hydroelectric dams, causing flooding and death. They can control hospital systems and kill or injure patients. They can control the airplane you're riding on while sitting in their seat. And all of these have been demoed at security conferences I've been to. I've seen these all in person.
There's a lot of physical harm that hackers can do. Sure, with a cop it's more personal since they're standing there in front of you pulling the trigger and a hacker doesn't even have to see your face.
Love them or hate them, both hackers and cops exist for a reason and are not going anywhere any time soon. One of the reason hackers exist is to point out dangerous security flaws like this. One of the reasons cops exist is because sometimes hackers are just as dangerous as the actions they're trying to draw attention to.
