Not sure what has happened, but I had a 2015 Model S 70 and I would literally get in my car, close the door and drive away. Now I've purchased a brand new 2018 Model S100D and sometimes it takes 10-20 seconds for the car to boot up. Not only is that annoying, but I cannot even lock my door from the touch screen until it boots up. For safety reasons, this is really dangerous (especially being female). Does anyone know why this is happening? I have friends with the same problem and some with no problem at all. I did ask at service and all they said was, "it's a software issue", "use your phone app to lock the door". No joke.
