I've had blind spot indicators on many of my cars and find them totally useless, because they're easy to ignore. A big red flashing is very easy to see (with signal on) or just notice car icons. I'm in Autosteer 90% of my driving so it's very simple to do either or both those things. With lane changes getting significantly better with the 2019.40 software release, I'm even using NOA a lot more.
I've had blind spot mirrors before, and I find them brilliant because they're difficult to ignore. I don't use NoA for every trip, so that's not useful to me. Because you use autopilot 90% of the time doesn't mean the rest of us do, or even can do (i.e. dual carriageway, non-highway use where AutoPilot is sketchy).
