It seems that whenever I am driving I've always got to pick my nose. I've also noted that other people do this on a daily basis as well. Why do people have the tendency to pick their nose while driving?

I'm thinking an NIH grant is in the works for this. – Chuck Sherrington May 21 '14 at 15:39

I suppose one explanation of this observation is that being a driver in a car is a semi-private space. It is semi-private in that it often feels like people can't see you. In addition, even if someone sees you, you will be driving away from them shortly. And it is unlikely that they know who you are and that your nose picking will ever affect your reputation.

Thus, presumably there are many activities that people tend to do more in private, that occur often in a car. E.g., random singing, farting, etc.
