I think there are a few things that posters here should understand.
1) Because other devices are potentially harmful does not make the Insight any more or less harmful. When somebody says something like, "How much emf is coming off of his montior," they pose an irrelevant question. If the emf is harmful from the Insight, then it is harmful, independant of exposure, or lack of, from other devices.
2) Just because someting does not currently pose a hazard, does not mean it is safe. I could smoke for 30 years with no problems and then die from it. The question of why there are not sick Insight drivers is not effective. Think blacklung, asbestos, Chernobly, UVA/UVB. Also, maybe there are sick Insight drivers, it would take some clever investigation to find a correlation.
3) The MRI question is also useless. How much time do you spend in MRI's? How much time do you spend in your Insight? As I mentioned in the 1st part, so what if an MRI gives off more EMF, does that change or have anything to do with the Insight's emf? Because Y is worse than Z in no way addresses the badness of Z.
I think investigation and knowledge, rather than useless comparsions and questions, might lead us to realizing this vehicle is less than heathy to drive, or maybe it will put our/my mind at ease. Sorry to be long.
