I'm thinking the kind of lead apron you use in a dentist's office to shield you from x-rays might work to shield passengers in an electric Vehicle

I have read many stories already about people having done this to their hybrids or electric vehicles. It would be a lot of work but basically you would need to (at the very least) put lead shielding directly between any electric motors (or generators if you are in a hybrid too) because both generators put out electromagnetic radiation when they generate and electric motors put out electromagnetic radiation when they are used at all. However, it's also true that the faster a motor is spinning (powering) the more electromagnetic radiation is going out in all directions. So, theoretically at least, you would get more radiation at 120 miles per hour in a Tesla than you would at say 10 to 30 miles per hour simply because there are no gears on a Tesla and the amount of radiation would likely have to do with how fast that electric motor is spinning in it's single gear forward or backwards. But, forwards you are going to be doing 30 to 70 miles per hour most of the time so this is when the maximum radiation would be received by the driver and passengers of the vehicle.

I think that driving in any electric car or hybrid might be like taping 100 cell phones to your body on your head and heart and other parts of your body including your reproductive organs while the smartphone was on whenever you drive. So, if you wonder why you might have headaches or be sterilized this could be it over time or when you have a heart attack or stroke.

Whenever I see a man with a smartphone in his heart shirt pocket I wonder how long before he has a heart attack or heart problems or dies. This is just how I think about all this. But, someone like this most of the time is sort of like a smoker of cigarettes. You can't tell them anything until it's too late for them to survive.
