Interesting tidbit: The Marine Corps is now deploying their new M-ATV, which is an off-road version of the new MRAP series of vehicles. The builder generously equipped it with lots of power ports/cigarette lighter plugs so personnel can use their iPods/MP3 players, etc. They figured that if they did NOT provide that kind of power access, the troops would just hack into the vehicle's wiring harnesses anyway. Car & Driver magazine has a report on it in the March 2010 issue.
