Not sure if you're being serious, but you have conflated 'it's a privilege' with 'no rights while driving'. You need a license to drive and getting that license takes away some of your rights, but not all of them. The Supreme Court has upheld fourth amendment rights for drivers, e.g. : http://en.wikipedia.org/wiki/Arizona_v._Gant
That being said, I hope this guy sues the hell out of someone to get this fixed.
I checked wikipedia, and evidently the Mac has something called a "Sudden Motion Sensor", it goes on the say that some Thinkpads and TravelMates have a very similar technology.
Which leads to the question, is there *ANY* such sensor on a desktop computer?
