Not for the majority of MS/MX cars with a build date prior to 09/2017. Tesla had pretty much deprecated the non-Plaid MS/MX line, including newly built cars. I.e. there is no technical reason why the blind spot monitoring could not work with the turn signal. It works if you pull it up when driving. Same for live view.
IMHO, we'll never see non-beta FSD. Elon has our money and refuses to talk to us. We've become a liability but even if so, he just doesn't care. It will be interesting to watch when (not "if") this happens to current M3/MY vehicles. Moles don't change their spots. History will repeat itself.
