Warn other people to stay away . Ask them to call 911 and the
local electric utility for help.
Stay there until rescue workers arrive. You are safer inside the
car because it acts as a Faraday cage.
If you must leave the car because of fire or other danger , DO
NOT STEP OUT of the car . If you touch the car and the
ground at the same time, you will be shocked . Instead, JUMP
away from the car so no part of you touches the car and the
ground at the same time. Land with your feet together, and
shuffle away keeping both feet on the ground.
Do not try to help someone else from the car while you are
standing on the ground. If you do, you will become a path for
electricity and could be hurt or killed !
Once you jump from a car with a power line on it , the danger
may not be over . Electricity can spread out through the ground
in a circle from any downed line . The voltage drops as you
move away from the point of contact . If one part of your body
touches a high-voltage zone while another part of your body
touches a low -voltage zone , you will become a conductor for
electricity . This is why you should shuffle away from the line ,
keeping your feet close together

Makes more sense to call them yourself.

Or just drive the car away so the power line doesnt touch the car anymore.

Yes, but it makes more sense to drive the are so it doesnt touch
the power line anymore.

Not if the protection systems have removed the power from the line.

Completely silly, and if its been raining heavily, and it often has
been when power lines touch your car, that wont save you.

Thats fantasy. Doesnt happen even with 500KV lines and even someone
like you should notice that they dont look like any old power lines.

But you have no idea where the point of contact actually is electrically.

Mindlessly silly. You dont see any of the power line workers do anything like
that.
There is a reason why they dont.

Will a cellphone still work in a metal box with several hundred kV A/C
circulating through it? (Especially if it is charging, or a hands-free
electrically connected to the chassis.)

If the car's electrics are still working.

Perhaps they usually turn the power off while working.

You wont normally get anything like that high a voltage on the car.
11KV is about as high as is likely. Thats the voltage thats used down
streets and those lines can get dislodged by some fool bringing down
the power pole or a big storm doing that.
The hundreds of KV lines are those on the huge metal towers.
Those lines dont often fall on cars, and the system automatically
turns the power off those when they hit the ground anyway.
> circulating through it?
It doesnt circulate thru the car. The cars body is insulated from the road by
the tyres.
The phone will still work fine with an 11KV line touching the car body.
> (Especially if it is charging, or a hands-free electrically connected to the

The 11KV line touching the body of the car will have no effect on either.
And it wont affect the cars electrics either.

Corse they will still work.

They dont actually. They normally work on them live, because
of the massive disruption turning those high voltage distribution
systems off to work on them. You can see them with insulating
mats on the wires at times.
