I'm not suggesting it had any function on that automotive functions, but I was also not aware of the media center reboot with steering wheel buttons. From what he described to me I don't think he was either, I'd have to check and will pass that along if not!
I'm a little surprised that the media computer doesn't have a built-in heartbeat check and know to reboot itself if it stops responding. I've heard of other cars and embedded systems doing that.
EDIT - asked him about reboot via steerling wheel:

- mav3rick 6y agoIt's called a watchdog. And it's 99% running Android and should have that.

- extrapickles 6y agoIt probably does, but you always have issues where the task that feeds the watchdog works fine, but another does not (eg: GPU gets in an odd state). In single core systems its somewhat solvable, but in multicore and if you want to include multiple chips in the crash domain it gets very hard with off the shelf chips.
- rootusrootus 6y agoIn my experience the couple times I've had a touchscreen glitch, the watchdog will activate and reboot it after a bit. It's not very aggressive, though, for sure, it can take a minute or so. > It’s not great because you lose lots of feedback. No speedometer, no sound from turn signals, etc. But it does work. Yep, this is very true. You are driving blind, as it were, because the touchscreen is the dash. Fortunately it doesn't take long to reboot, but it is still much less than ideal.
