I lead software and product design teams for a living and I’m terrified about a steady stream of OTA updates, other than data/content. I’ll bet that we have to visit our dealers for at least 2-3 years for substantial, core updates to PCM and that as Porsche gets more experience, they move more of the platform updates to OTA. One issue will be the sheer size of the codebase and delivering that over LTE connection if customers don’t have WiFi coverage where they park their cars. What gives me hope is that unlike PCMs of the past, it appears there’s very little of this generation have functionality burned into ROMs, so updating the entire UI of the car, across all the screens, should be possible.It's clear, though, that unlike Tesla, not all updates are OTA. That more conservative approach isn't a bad thing (bricking cars is something I'm sure they want to avoid), but it is less convenient, and over the nearly 8 years I had a Model S, I only had a single software "delivery" issue (an update that wouldn't install) that was solved with a single email and one button press on their end.
One area I’m curious about is whether the dashboard, PCM screen and lower control screen are managed by one system and set of software or if they’re independent systems on separate stacks with separate runtimes.
