I’ll fill you in on some insider software experience. I work in the medical device software field, with a focus on R+D for new devices and technology. The number one mandate? Get products out the door and into the market on budget (as cheaply as possible) and as fast as possible. Billions in market research shows that you will sell and make exponentially more profit by being first to market with new promising technology, even if that technology is covered with non-risk (very little risk of injury to user or patient) bugs. We have bug reviews every day of what is discovered, and while any bugs with injury risk get addressed immediately, about 90% of the non-risk bugs get pushed until after the initial market offering. Turns out, you may anger half of your customer base initially, but only a small margin actually return the product. The rest deal with it in the hope that it will be eventually fixed, with the comfort of knowing they have the newest and most advanced tech on the market. The plan is, of course, to eventually fix all of these issues and send field patches, but only after selling the majority of the units and getting a jump on the competition.
I do not have insider knowledge with vehicles, but I imagine it is the same way. They probably knew of nearly all of these issues before even making the first consumer vehicle for 2019, but they were almost certainly not going to miss out on a massive head start on the competition by delaying the release until all issues were fixed.
Yes, the 12” display will have a lot of bugs initially; enough so that I passed on it when I ordered mine. However, if they want to keep selling it in the coming years after other manufacturers have released competing displays, they know they need to fix the bugs. Unless the market rejects the displays and they are a poor seller (extremely unlikely based on the little data they have so far), they will fix these issues at least by the time the competition catches up.
