Electric Wires Falling on Cars
I am a Defensive driving teacher. How would you talk to
people about hot wires falling on their car? Can they touch any
thing in their car as long as they are in the car, (like seat belts,
will, door, etc.) or will they get shock?
Should not be a big deal in any case, because the frame and body of a car
are a "Faraday cage," inside which there is no electric field. if they
are inside the car and the car contacts a hot wire, they should try to get
the car OFF the wire. Touching anything outside the car would be a very
bad idea. That also means do not leave the car until it is no longer hot.
This works for metallic cars only.

I was always taught that you can touch anything as long as it is not metal
and/or connected to the frame. That being said, I would never do anything
that would remotely make my body a possible path for electricity. The safest
bet would be to touch nothing and just use the cell phone if it still works
and call for help.
