Perhaps Tesla do have it right here, with firmware you can update without a dealer visit. It would not cost much to WiFi/Bluetooth up your car, and allow an O/S update via your broadband - as on an iPhone, SmartTV, SkyTV set-top box etc.
@Neil Postlethwaite So, which is it? Firmware or O/S update?
"Firmware is held in non-volatile memory devices such as ROM, EPROM, or flash memory. Changing the firmware of a device may rarely or never be done during its economic lifetime; some firmware memory devices are permanently installed and cannot be changed after manufacture. Common reasons for updating firmware include fixing bugs or adding features to the device. This may require physically changing ROM integrated circuits, or reprogramming flash memory with a special procedure."
If firmware fixing is how a problem or issue is to be resolved, then, neither Tesla nor any other manufacturer would have it right.
Rubbish - I do firmware updates all the time at work to computer/server main board BIOS, RAID cards, ILO cards and other devices like touchscreens on PoS, and the same happens to Sky TV boxes, Synology NAS's, Samsung TV's etc. OS/Firmware is pretty much interchangable these days.
I think you are retro'd back in the 1980's with your TRS-80 or BBC Micro.
@Neil Postlethwaite @adornoe I'm not arguing that it can't be done. I'm saying that, neither Tesla nor any other manufacturer would have it right, if it requires that a firmware update be done. That means, taking the vehicle to the dealers or automaker's repair shop. Tesla did have a "remote fix" for a battery problem recently, but, that didn't require a visit to the shop. Messing with the hardware and/or firmware, is not an ideal situation.
