G'Day All,
It is absolutely not the case that "anything with an operating system needs to be re-booted on a regular basis" IF it is in proper working order. I don't count th edefective Microsoft OS as software that works correctly, btw, as just one instance :smile: If this is still happening (as it is), then it indicates a flaw in the operating system code (we coyly call these "bugs" - how cute - the moth in the relays and all that). However, this is a flaw and it needs to be corrected. It is clear in the history of the Model S that this flaw has existed for some time (years?). I suppose (expect) that Tesla is working on that since they should have been informed of it since 7.1 rolled out if it has happened to a number of users.
Can you imagine the level of "confidence" that consumers might have in the banking system (ho ho) if all the ATMs in Australia needed to be regularly rebooted? Do you think it would be acceptable to take the big iron in the basements of various main branches of the big four banks off line for a "reboot" to cure a software flaw (bug)? How secure would you feel if the CBA were to reboot the lot tonight to reinit after curing some fault in the operating system and you were unable to access your accounts in the morning, or even if it were just the web site were down for an hour or two? "It's all working fine sir, you just can't see it". We've all had that sinking feeling when a web page refuses to load.
My PC runs Red Hat Linux (Tesla uses Debian Linux I believe). My PC does not need to be rebooted frequently, or at all, to "cure" software faults. This does not mean that it is perfect. It means that faults in the software can be fixed while keeping the OS on-line at all times. We have become far too complacent about this sort of software behaviour and it is unacceptable in mission critical systems of any kind. I see the main screen of a Tesla car as a potentially mission critical system.
Now, apart from this point, Tesla (and all of us) need to be mindful that they (on the big stage) and each of us, (in our small way) are trying to convince a fossil-fuelled world to morph into an "electric world". We will not be given much leeway in doing this. The slightest little thing will be pointed at and picked on. When Model 3 hits the road it simply cannot have a flaw like this in the operating system. One or two instances, maybe you can get away with that. Every car manufacturer does. If it's a few thousand then you have a mass "panic" as though the brakes had failed. or caught fire, or some major catastrophe had happened. That is how the competitors wil portray it, and, no doubt, some media pundits as well. You can see the car-press head lines.
There will be no rational public reaction if this happens in over 500,000 vehicles at the rate it has happened with model S, no matter how safe the underlying functionality may be. That is why it is important to have such visible flaws in the software corrected, or, if not corrected, then recoverable automatically and immediately, but preferably, corrected.
Apologies for the bit of rant, but a car as terrific as this should look its best at all times. I can't stand the thought that it would be "marked down", or prospective buyers turning away, after hearing about curable defects like this.
Regards,
Gary
