Tizen
It's basically Samsung's Tizen. And we all know how popular that is...
I can't help but feel that we're sleepwalking into another bunch of unnecessary security woes, just like has happened with the Internet of Things. Nor is that thought aimed solely at automotive grade linux.
The last thing any of us want is a flat battery caused by some bitcoin mining malware that's found its way onto the infotainment system in our cars. It's happening to our thermostats, smartTVs, set top boxes, fridges, etc. Why would our cars be immune?
Also a car system would be a rich target for cryptolocker type malware; "You wanna drive this car then you're gonna have to pay". That kind of threat doesn't work so well for, say, a set top box; we'd just throw it away. But we won't throw away our car just like that.
So if the car industry wants to pick up this then they're going to have to get smart with continual updates, software security expertise, all the expensive things necessary to keep an Internet connected system safe these days. They're not used to providing that level of support for software.
