      Have you ever run a software upgrade to another brand of car? I was once present when a BMW was updated and it took 40 minutes to scan the CAN for all of the control network members, after which the update could start.

        Shitty design is still shitty design, even if all car makers are bad at it.

        And I’d bet it comes down to hardware decisions that ended up saving tiny percentages of the total cost.

          It’s more the opposite. The hardware level updaters, are usually small pieces of non-updateable code called bootloaders. These are purposefully made small, slow, and ROBUST. They do parity checks on everything, status checks, store local copies of data transfer in weird esoteric ways to not be disturbed during the actual update.

          The issue is that you can make it work 99% of the time without issue way faster. But bricking a car that then has to be towed for free to a service center and flashed is super expensive. So the fix is slow and robust updates that happen when the user isn’t even there.

        Yep, my ford took 25 minutes to do the update that added Android Auto, after 2 minutes of downloading it to a USB stick. The car only has USB 2.0, so that could be a factor though

      My VW Passat took the whole two hours it took me to drive to my parents house. Had to sit in their drive for 15 minutes for it to complete.

      It was just a maps update from DVD.
