It's worth noting our regular cars have locked down ECU. I had to pay good money to be able to get around it. But I agree it's not great overall and isn't headed in a promising direction.

    Even my 2005 Audi A6 had software locked features.

    Some were probably tuned for different markets, like lock confirmation beep, but others were added as later model year updates like visualization of parking sensors which, IIRC, was added with the 2006 model year update.

    Now, granted, the Audi dealer that had serviced my car prior to my ownership never bothered to install firmware updates, but even when I did it was off by default.

    To update I needed to flash new firmware onto the ECU’s using 3 CD’s with various updates while the car was hooked up to a charger. The whole thing took about 3 hours.

    And then I could use a third party diagnostic tool (VCDS) to set and enable the visualization of the parking sensors. Honestly can’t remember if it actually worked, but at least I got other features made available due to the software updates.

    The problem, IMO, is the trend towards never owning anything - not software gated features.

    And that trend is certainly negative.
