This is a serious issue, but so far I haven't seen much evidence that anyone with the power to actually do something about it is actually doing anything. Cheap electronics has made it easy for companies to add all sorts of crap to products that we don't really need and lived quite well without for over a hundred years, and now the average vehicle is viewed as more of a platform for electronic toys than it is a means to get from here to there. Just look at the advertising for cars these days, and 99% of the emphasis is on the infotainment systems, the keyless security and ignition systems, opening your liftgate by waving your foot under the bumper, etc.. Every bit of that has nothing to do with the real purpose of the vehicle, but consumers now care more about the toys than they do the important stuff like how the vehicle actually drives, handles, and all that other stuff that used to be pretty important.
The part of the story I really love is how the bureaucrat mentioned coming up with new regulations to address the hacking issue. When I stopped laughing, I thought about finding a way to contact the idiot and mention the fact that his employer can't even protect the personnel records of it's 24 million employees from Chinese hackers, so I doubt they can wave a magic regulatory wand and protect millions of vehicles from hackers.
