Pulling out your phone to unlock the car (as demo'd in the keynote) is no different that pulling out a physical key. Until 3.0 comes out which adds BLE to NFC this is DOA IMO. Why pull out my phone to hit an NFC tag when I can keep my fob in my pocket and unlock the car by pulling the door handle? Only works with cars that have Comfort Access (or similar if non-BMW). My cars since 2015 have all had comfort access, having to pull my phone out of my pocket would be a big step backwards. My understanding is when 3.0 comes out you will be able to keep your phone in your pocket, purse, backpack, etc.
Its a place to start, I get that, but if you already have comfort access (or similar) your not missing much here. Sure, being able to send a digital key might be handy but only in very limited circumstances.
