Software glitches...

"That's not a glitch, it's a feature!"

Couple things I noticed about the center stack, and one about the rearview camera mirror.

The display is generally nice, the adaptation for light/dark, especially with the ambient lighting, is nice. I'm used to, and generally prefer a driver oriented *very* basic info setup, so this is....something different. The huge geek factor is mostly for your navigator, imho, while you keep your damned eyes on the road. I don't really want to see all those pleasing graphics while I'm driving. Looking forward to playing with the settings more, but for now, I hope my AWD Bolt SS (there I go again) will have a minimal, driver focused setting, along with its sport suspension, better tires, and Recaros.

There was a software glitch moments after driving it out of the showroom. Backing it out of the tire bay after the winter tire install, the backup camera didn't come on, no birds eye view, and the center stack screen was frozen. (Mostly I was pissed I couldn't turn on the seat heater, it was damned cold.) Didn't seem to be anything I could do to cancel a screen, etc. Huh.. Moments later while driving, the center screen auto rebooted. Haven't heard that reported elsewhere, and hopefully it'll be an isolated occurrence. I'm sure it's Version 1.0, or something close to it.

Noting this event with the dealer, I asked about updates to the software, and per my service rep, these will come over the air via Onstar, regardless if you've purchased a data plan, for the first 3 years. (Unclear what happens after that, but hopefully they'll have ironed out the software by then.)

In case you're in the dark as I and my salesman were, on the premier you activate or turn off the rearview camera mirror with the same tab that you would usually darken the mirror with. It's a pretty bright, good resolution image, but for me, if you leave it on, it has the effect of looking backward on a train....nauseating. And all those things now behind you clicking along in your upper right field of vision are somewhat distracting, imho. I'll probably leave it off until I want it for backing up. Otherwise it's just like a little TV screen staring at you playing what's behind you while you're trying to focus on what's in front of you. The setting I'd like to choose, Chevy, is for it to come on when I'm in Reverse, and off when I'm in Drive (well, Low).

Good thing it started working after driving a bit. Since it auto rebooted, does that meant the Bolt has some kind of fail safe that reboots the system automatically whine it sense a problem? That's sounds pretty handy even if we'd like to never need the feature.

Seems so, and I agree, I'll let you know if it keeps happening. I hadn't signed up for Onstar yet when this rebooting happened, so I would say it could have been doing an update for itself, but there was no such notification, and it wasn't registered yet. Since I don't think there's a restart button it would have to have some way to reboot. Essentially it's a little computer, probably suspect to hacking.

Are you saying you think your Bolt was possibly hacked? Really?

btw, any modern car is "suspect to hacking", not just the Bolt.

No doubt and this will always be the case especially with systems getting more and more advanced. Advancements might just mean more vulnerabilities... but who's to worry?

Anyone looking for more insight on this should watch this:

Wow, no, I said it rebooted and it's a little computer. Thankfully, it apparently reboots itself, and can receive over the air updates via Onstar. Like all computers, it's suspect to hacking. I don't think it was hacked, I said I think it had a glitch. No conspiracies here.

This is actually a concern of mine. The Bolt will be the first car I've ever owned that will have no driver overrides. It will be the first car that I don't actually physically control. It's also the first car I've ever had that's online and potentially accessible to anyone in the world.

In any of my previous cars, it the the throttle were to stick wide open for some reason, I could always take it out of gear, or try to override it with the brakes, or turn the ignition switch off, but on this car every single function is electric and controlled by the computer. We don't even have a manual parking brake anymore.

Two things I'd love to know are, how much manual override capability is there and how can I take my car offline? In the current world where we as a people seem fascinated with autonomous driving cars, we seem way to eager to give total control to computer chips and risk our own personal safety. These are the same computer chips, connected to the same internet that brings us frustration now.

I personally don't need my car "linked in" and don't want to be just a passenger.

Not true about the "No driver overrides". I can't find the exact forum link (posted by a GM engineer on the gm-volt forum), but he basically said the Volt (and Bolt...and all modern GM vehicles) have some "push-through" fail-safe....basically, even if the car powers off and is completely dead, if you stomp the brake pedal all the way to the floor, there is a mechanical link to the master cylinder which will engage the disc brakes manually.

Now, if someone cuts your brake lines too? I think you are fooked.

Sure, in case of power loss, I'm sure you can still steer and still brake, but what about if the power can't be turned off and the computer is in control? The ABS and the Stabilitrac are able to apply and release the brakes via computer, that's how they work. To what extent I don't know, but you have to figure that GM designed this car to eventually one day be autonomous as they keep hyping they're going to do with Guiney Pig Lyft drivers. This implies that the computer will have 100% authority to fully apply the brakes as well as fully release the brakes.

My guess is, GM has already equipped the Bolt with the necessary hardware for autonomous driving. It's just waiting for the software. I'm sure the brakes and the steering have mechanical linkages to the driver, but how much they can be overridden and how effective the brakes are against uncommanded full throttle, is a question I hope they have asked.

This isn't just about the Bolt, or GM, it's about all the new cars as we race towards being just passengers and systems monitors with arms wide open in embrace.
