Car Computer

In light of the recent revelations that car computer systems may be "capable" of catching viruses, what does it mean when you say "my car crashed"? :) As car makers are taking the risk "seriously", car "crash tests" will now probably include crashing the car's computer. Also, there used to be a joke about how computers were unreliable and needed to be rebooted all the time (you know who's fault that is), and that if the auto industry had the same quality standards, we'd see many more traffic accidents. Now... heh heh heh. Anyway, I'm puzzled why entertainment and navigation systems should be intertwined with critical engine control systems. Keep it separate, keep it safe. Like my windows box never needs patches or anti-viruses as it's not on any network, and is not used for anything other than one game, and storing digital photos. Oh... what a waste of a 2.8 GHz machine!!! If only they had Picasa for the Mac and/or Linux. Grr!!! (hmm... would it work with an Mac-Intel machine?)
