At the delivery day event, Elon is seen showing the new owners how to open the door by pushing the small button at the base of the B pillar. This happened almost every time. He can be heard at one point telling one driver, a Tesla employee, to put it in park.
It's worth noting that on the Tesla video about the CT features, they do cover this. Obviously, these folks were seeing this for the first time so can be excused their ignorance.
