It's just like in my model 3 or my wife's Teluride, the info screen/software can lock up or get stuck in a weird state and both have a way to reset it.
Normally neither would be a big deal, I push a button(s) and the screen goes black, it comes back up, again no big deal but at least with the Teluride, there's a the instrument cluster and heads up display to show your speed. I'm assuming the cyber truck is like my model 3 where the speed is only shown on the center screen. If it take's five hours over the minute of downtime, well that's going to be a problem. That said, in my model 3, I've only had to do this a handful of times on my model 3, mostly because the radio isn't working and only once on the newer Teluride because the map was stupid.
Jesus I thought the software on my ford was bad. And it is bad but it doesn't randomly stop working for no reason and have a reset button to fix it. It just doesn't break.
Oh, so an actual reset button like on a PC! Its existence alone is admitting that the firmware is shit. An embedded system should never freeze.
But admittedly, most car infotainment systems freeze/crash occasionally nowadays. Mine as well but it went with the Microsoft BSOD "solution" and restarts automatically.
Yeah, most infotainment systems hide their memory leaks behind the fact that when you turn the car off, you reset the computer. Not so in an always on EV.
So I'll push back and state that infotainment systems aren't embedded systems, more akin to a phone OS with the wide array of UX applications.
But yeah these infotainment systems are often left running on newer cars for connectivity and other features and just like any other OS, leaving it up and running is going to slow and get unstable over time for to memory usage.
Like I said, mostly not a big deal unless you're a Tesla and critical information is there and you didn't regression test properly.
My $200 Chinese android system doesn't.
