I do not think that either, but for some reason the Trifield was used for this test.
It is likely that the measurements were done without the wheels turning, but while driving the mesasurements can go up a lot, depending on the tyres, although the frequency will be low and the waveform not digital.
Also the background fields from outside must be taken into account, this is obvious but easy to forget, especially when hitting the road.
The ME 3830B will probably give a lower reading for the same signals, so one has to keep that in mind when comparing results.
When emf-exposure is the most problematic issue in a car, i would not care much about safety features and so forth.
And in fact cars that give high levels of emfs are the most unsafe for sensitive people, also because it affects one's awareness and driving-skills and demands extra attention.

Laura, I just wanted to add that another thing that I would recommend for EHS is to use metallic tint and tint the whole car. If you can find transparent film and someone who can put it on the windshield also, it would reduce RF a lot when driving by cell towers.  

It's hard to find tinters who still use metallic film, but there are some still.. they will warn you it interferes with radio waves =)  Solargard HP Quantum is a full metal tint that has very good reviews for lasting forever too.

Fully shielding a car from outside RF is probably almost impossible.. but the tint cuts down a lot of it still. I'm surprised there is more worry about the car fields than outside fields, as the outside ones are likely stronger.. especially driving beside powerlines, under powerlines, by antennas, by police radar, etc. I believe most police cars have the radar on constantly, and new cars with collision avoidance have radar on constantly as well.

You have to take that into account as well when testing a car,.. don't accidentally do it next to a power line, or an underground powerline.

Okay thanks for the tip. In my husbands vehicle the backseat levels are lower in the magnetic field readings. It seems all vehicles are different.

Keep in mind that magnetic field from tires increases as the speed of the car increases.
So you must measure when the car reaches it's cruising speed.. The faster you drive, the stronger the magnetic field.
Also, measure against the bottom seat cushion, all the way toward the back.. that is the closest point to the tire.
I think you would feel it if it's worse anyway.. so what feels best to you.. but as far as measuring, that's how I would measure it.

Yes driving is incredibly unsafe for people who are sensitive due the emfs as it affects your mind and ability to concentrate and depth perception etc, but from personal experience the newer safety features actually saved my husband from having a serious car accident so I am hoping it might be possible to have both, but maybe not we will see! :)

Yes I have noticed that acceleration is the worst for me... and higher speeds make sense as well. The more power the higher the fields

Definitely don't want a car with radar!!! Some safety features but not the ones which would cause more radiation. More shielding wouldn't hurt but my biggest problem right now is that I can't drive the vehicle I have due to the magnetic pollution and need to find something drivable with acceptable magnetic fields first :)

The radar from newer cars, when they are driving behind your car, will send the radiation to you. That's what I was trying to say.

Just be sure that it's not more than the magnetic field that causes the problems.. or you may try all the cars and it still won't work.. but if you had it shielded for example, then it might have.

If you can go outside walking around on the streets you would drive on, and feel nothing at all, then you could rule that out though, it must be coming from inside, not outside.

Instead of mu-metal i experimented with a cobalt-based foil , YSHIELD MCL61 , which was more easily ordered and seemed a better deal, although still 100 euro for a 0.6 m2 ( 6 square feet ? ).
However it appears to shield usually 10 to 20 % of the magnetic AC fields instead of the promised 97 %.
In one case ( covering a linear charger ) it shielded 55 %, but even that is a far cry from the specification ( a factor 15 ).
From what I've read, none of the high permeability ferromagnetic alloys (MuMetal, MCL61, electrical steel) will give you 97% attenuation in just one layer. You need multiple layers with gaps in between them.

MuMetal also has lower saturation than electrical steel (a special type of high-silicon steel), so if the field is strong, you may be better off starting with the latter and then using MuMetal or something similar to mop up the last little bits.

I wonder, is there a difference between 2WD and 4WD? My car just died so now I have no choice to replace it and go look at cars today with my meter.. should be an interesting experience with the sales rep... Grab a bunch of keeps dude we have to measure a bunch of cars... lol. I was thinking of maybe getting 4WD I am curious that maybe with 4WD maybe the fields wont be as high on the drivers side floor???

Or the difference between front wheel drive and rear wheel drive??

I have a 2017 AWD and at the driver's torso, the level is around 11 mg with engine running. If accessories are on (including A/C), and engine is off, the level is around 0.5 mg. The passenger side is low except at the feet, of which both sides are off the charts. Interestingly, the rear seat behind the driver is even worse than the driver's location.

Now I'm wondering if AWD is the extra source of EMFs. Apparently, the brain of the AWD system controls an electronic rear differential and the supply wiring might be the source of the high EMFs.

Hmm I don't know I tested about 25 vehicles yesterday and going back today to test more. It didn't seem to matter if it was 2WD or AWD on the ones I tested. And it is definitely mainly the engine/brakes that are the issue because as you increase speed or push on the brakes these readings go way up. So far the best 2 vehicles I have found is a huge 8 clylinder 4WD Ford F-350 truck which is a bit too much vehicle for me and also the small electric cars which surprised me. Virtually no magnetic fields unless you are driving, and if its city driving the readings only went up to around 2-3 mg on the driver floor. Higher speeds will increase this. I have heard so many bad things about electric cars being high in EMFs but thats not what my meters showed. It was exactly the opposite.

That's a bummer. I was hoping to find some type of correlation. Ford trucks seem to have good readings. I think I read about someone shopping for vehicles with low EMFs and they settled on an F150. It certainly doesn't sound like it's 4WD or AWD that causes a problem. I'm not surprised about EV's having low readings. It's been several years since the fuss was made about them possibly being dangerous. Apparently the manufacturers have listened and acted accordingly. Unfortunately they turned a blind eye to conventional vehicles. I tested a couple SUVs recently and they had really high readings. Have you tried any Kias?
