It's just a chroot. Thats far less dangerous than completely reflashing it etc

So what happens when your app hits an infinite loop and locks the CPU? Or trashes some memory it shouldn't? Does autopilot still work? Do the airbags still deploy? Does the brake still work?

It should. In a world where people routinely talk/text/drink and drive I don't think we should expect 100% from electric or self-driving cars.

I cringe from the PR implications as I say this but really I fully supported Jeb! when he shrugged about one of the shootings. If we want freedom, we will have some missteps. I kind of wish we could say the same about religious extremists but that ship was always under command of the same bigots who controlled the conversation during the red scare.

I wonder what happens when you get into a bad crash, somebody decides to sue, and it comes out that your car was running modified software. Would you be exposing yourself to any liability?

I can imagine a few ways that you could.

Say you installed a media player. Now you'll have to convince a jury that you didn't install a media player just so you could watch videos while driving, and therefore were distracted at the time.

The safety-critical stuff is not running on that computer. So the brakes still work, and the airbags deploy, for sure. I'd be very surprised if the autopilot is on there.

It is an interesting question. A while a go, 2 guys made a presentation at DEFCON with a presentation about their findings on hacking a Tesla Model S.

They were able to successfully get root access to the car's system (not chroot, real full root access) and with that they were able to fully access to the car's API within Tesla OS. They even showed a video about one of the guys driving the car at low speed and the other one remotely accessing to the car's Linux shell by SSH and shutting down the whole car while the first guy was riding.

The interesting thing is that for higher speeds, for example more than 50 km/h, the car seems to override any of the Linux systems and the root access becomes useless, it stops working.

In another words, the car is able to decouple itself from the Tesla OS.

You can check the presentation from those guys here: https://youtu.be/KX_0c9R4Fng?t=39m51s

Dude you are my hero. I look forward to the day that I can sit in my car with my friends, smoking something, watching a movie, and letting the self driving vehicle wander around LA while we look for interesting places to stop and explore. I would never use my couch again. Edit: If tesla begins making showers I may not even need an apartment.

If you cared to read the article, it's a girl, not a dude :)

Women can be dudes too.

Yep. Jeep Cherokee was hacked by connecting to multimedia system which supposed to be separate from driving system, yet our wasn't a problem.

All they had to was reprogram one of controllers and full access was granted.

Even if you don't reprogram controllers you don't have guarantee that some components won't go high wire when your modded version dies something different.

The best approach would be if manufacturers would provide an air gap, but they probably won't, to save costs.

Context for some of the jokes: https://fun.irq.dk/funroll-loops.org/ Internet culture throwback.

When I was 15 I started my linux days using gentoo, back in 2003/2004.

While the hassle of compiling and all the effort it took is laughable looking back on it, I still credit it for teaching me the command line and unix in general, these are skills I carry though with me to this day.

Massad Ayoob recommends against [0] using a defensive firearm with, say, a modified trigger due to potential liability. [1] This situation seems similar.

I can't tell if the pull quotes are satire or not. "With Gentoo, my 5s 0-60 is so much faster than your 5s 0-60." Combined with the stated 3 day compile time, I'm thinking yes? Maybe?

It's a reference to this: https://fun.irq.dk/funroll-loops.org/

That's immediately what I thought of as well, but I didn't want to, um, insult the blogger.
