I was wondering if anyone with a Model S is sensitive to EMF and can comment on whether or not the S is problematic for them (EMF-wise, of course).
If you search on 'EMF', you'll find a lot of information already ... here's a good starting place: EMF Radiation
A good friend of mine really wanted to have the S. He drove the car at Menlo Park and would have taken a "floor model" the same day. Unfortunately, he developed too much of a headache and you really can't turn the 3G off. Sadly he passed...
Kleines Bild Johannes Gutenberg-University's study of EMF-scare "The nocebo effect: media reports may trigger symptoms of a disease Expectation of negative effects can increase likelihood of experiencing symptoms / Media needs to be more responsible when warning about health risks."
The power of the electromagnetic field radiated by any source attenuates with the inverse of the square of the distance. Since I suppose that the 3G electromagnetic field is radiated with a power less than 2 W (as every mobile phone at least here in Italy) I think that it shouldn't give any effect to human beings.
I have had issues with cell phones, particularly the early ones and headaches. I am also sensitive to very high pitched sounds. I have not noticed any issues whatsoever with driving the model S. ... my neck gets a little sore, but that's from punching the "gas", ;~).
I can hear high pitched sounds well above what most people can, so I feel your pain on that front. I used to hate it when stores had cheap tube TV anti-theft monitors, because the screams of their horizontal flyback transformers were like nails on chalkboard to me. Fortunately no one uses those things anymore. I wouldn't be surprised if the early phones were making some high pitched noise.
