I know it sounds crazy. He told me that he has personally seen adcoms look at this. He said there was some applicant whose dad drove him to the interview, and in the adcom meeting, the dean of admissions brought up that he wouldn't fit in at the school because he doesn't have a drivers' license. Furthermore, the adcom took this as evidence that he was unable to take care of himself.
It sounds insane to me too, but then again, with admissions being so competitive, I guess they start to look at little things like this?
