Today I met with Matthias Kranz in Munich. Besides discussing his thesis I got to see his new car (a prius) – quite impressive and interesting interfaces. Later I met with Wolfang Spießl who started recently his PhD in cooperation with BMW - again seeing an interesting and impressive (test)car.
It is really curious to see that there is a lot of interest in the hobbyist communities on car interfaces and protocols. In the June/2007 issues of Elektor (http://www.elektor.de/) was an article on a OBD-2-analyser, in a recent issue of the EAM (http://www.eam-magazin.de/) was a similar article and there are many community sites on the WWW, e.g. http://www.canhack.de/
Perhaps we could do in one of our pervasive computing related classes a project on this topic? There are so many technical opportunities and the challenge is to find the convincing applications!
