Totally get where you are coming from BertL. This seems like it is falling on deaf ears and there is a distinct possibility it is.
I don't want to make excuses for Tesla but I do think it is important to acknowledge that the development process can be quite lengthy. We gave our collected feedback very late in the process for 7.1. In fact, we gave them our last update on the 5th of December right before the holiday break. They delivered the SW update on the 13th of Jan! It will be most interesting to watch for the next update and see if the desires of the community are addressed more substantially. There were some very minor tweaks that seem to indicate someone is listening (or at least someone is actually connected to sub-systems we are interested in updating).
FWIW, it seems obvious that Tesla will not acknowledge feedback specifically. That said, were I product manager or engineering leader for Tesla I would look at the input to get a sense of focus areas. Many of our requests were not very well thought out so it is likely a bit of a struggle to consume them. I want to be clear that I am one of the ones with poorly expressed ideas. Some of our requests appeared to be quite difficult to implement as well.
It is important to reiterate that all developers are not fungible. Getting wrapped around the axle (pun not intended but I got a chuckle out of that) about why their autopilot engineers do not fix the media player to our liking is not very useful. Bringing in a large group of new developers takes time. Writing and building code thoughtfully for the future takes time. It seems quite clear that they are not staffed for rapid and wholesale updates to the entire code base. You may, or may not, be shocked to find out that the traditional development process is incredibly lengthy (18 months is the norm for traditional product development). We can hope, and I believe, that Tesla is more advanced than that. But, even so, building a solid infrastructure that will play out well for the future requires a lot more work than most think.
Thinking through the above indicates that waiting for the next minor release to see if we have had some impact is probably the best strategy. Post the next minor release it would be good to redo the feature/fix priorities and see whether we have something substantially new/important to ask for.
