Has anyone any concerns over this or know if the Enyaq has anything to protect the occupants.

Where I work we use EMF shields with cooling fans around drive motors in order to prevent interference from the motor windings causing issues in associated equipment. We also do it to servo's where magnetic fields are detected to reduce risk to the couple of people in our factory with pacemakers so surely its a relatively easy fix.

I haven't read such a load of tosh for ages :) It's almost as if they want to sell you some tin-foil to wrap round your head. The levels of electromagnetic radiation in a car is way below the levels that can affect health. The article says wifi is dangerous - no, it's not and there are thousands of studies that show that, compared to every one that says there might possibly be a link. There's a big difference between the short pulses of wideband RF used in wifi at milliwatt levels and the 1000W of concentrated RF energy in a microwave oven, yet they think they're the same thing. Radio frequency stuff was a big part of my electronics degree, so I do have a reasonable understanding of this.

Electric vehicles do have to comply with UNECE EMC regulations. There is shielding where there are high frequency alternating currents (inverter and motor(s)), but most of this is outside of the passenger compartment, so shielded by the bodywork. Even then it's relatively low amplitude. The radar and 4G modules obviously emit radio waves, but also very low power, well within guidelines. I find car radar interesting, as it's so low power (range is under 100m) that it can almost be considered a passive system. Certainly nothing like what aircraft use.

Absolute rubbish, just scare-mongering in trying to get you to purchase their product. No better than many other scams in all honesty.
Here's the alternate (and more scientific) view point:

A rather old article, but seeing as the technology has moved on significantly since it was written, it's still mostly relevant:

I work in industries where operators are inches away from large servo drives and have done for decades working 12 hour shifts and not heard any issues except those previously mentioned, not cancer.

I've seen several discussions recently on performance car forums where people seem to use it to confirm bias against electric cars.

Not sure about electric cars exactly, but EMF is a real issue. We just don’t know much about it.

Hey, guys. I know why you’re joking about it, cause I used to do it too until I got seriously ill. In short, it began about 10 years ago when I got my first phone and computer. I noticed having terrible headaches, especially when I left my phone in the room for a night. My Dr told me I was too sensitive to EMF. She recommended wearing special emf clothing to protect me. The headaches went away in 3 days after that. I first put on that clothes 7 years ago, and I still wear it everyday. Maybe I’m too anxious and sensitive, but it’s my story, guys. A true story.

There have been studies in the US on people who have moved away from cities to avoid EMC - there is a town where mobiles and WiFi are not allowed.

They found no connection with EMF and headaches or sensitivity - but there was a connection when the test equipment operation was visible to the test subject. The test was set up with EMF generators hidden in a cupboard next the subject and bogus "test equipment" with lot of flashing lights (or not) clearly visible.

You should find the Universities researching this and write them - they must need subjects to do testing.

There was legal case against Orange (now EE) who installed a base station on top of flats. A lady on the top floor suddenly got crippling headaches and died. Orange pointed out in court that they were still waiting for the electrical power feed to be connected to the system so it hadn't been turned on and commissioned.

well how 'bout that? exactly the same story to the letter, as a "legal case" against Telekom in Germany...
and one in Spain in 2002
and one in Ireland in 2009

fake shit that is.

I wouldn't recommend a trip to a hospital's MRI machine if this worries you..... :)

Only as fake as any normal newspaper report - I remember reading the reports at the time. I can believe that these things are quite common with the prevalence of the "No fee accident compensation lawyers" we have now, and the huge number of base stations that have been installed. All it takes is for a technically gullible lawyer to see the temporal link between the base station appearance and an unexplained illness to initiate an action, and all it takes for the mobile network to knock it down is to show that the symptoms predate the base being powered.
