The notion of nearly all things being networked almost all the time has been with us for over two decades now. Most networked entities had been fixed until the advent of cellular telephony. With cellular phones the fringes of the information age have begun to expand in pervasive forms. Adding the automobile to this context adds a new dimension to this domain of pervasive networks. In this chapter we introduce the notion of a mobile networked embedded systems (MNES) in which a mobile entity such as an automobile is composed of internally as well as externally networked software components. We further discuss the challenges going forward of designing a MNES-vehicle with regard to security, privacy, usability, and reliability (SPUR).
