a minor wise point here -
if you are ever in your car and a storm causes electric overhead

NOT MOVE, DO NOT GET OUT OF YOUR CAR - you are in no real danger

Correct.
- the metal of your car is ELECTRIFIED but the tires will
prevent it from burning since they act as a nice insulator.
Incorrect. The tires are not made of pure rubber. They are made
from a blend of rubber, synthetics, metallics, etc. Then there
are those pesky steel belts. IOW, your tires are *great*
conductors. They are (luckily!) NOT insulators.
You don't get electrocuted, as long as you're inside the car,
because the current is passing thru the metal chassis, thru the
tires, to ground. Some of the current is going thru you, but
it's a trivial amount, as electricity prefers the better route -
thru the tires to ground.
It might be worth mentioning that the car acts as a Faraday (sp?)
box whereas most of the voltage/current remains on the outer
perimeter.
The way out of this is NOT TO STEP OUT as that will complete the
electrical circuit and you will be toast.
Correct. If you were to step out of the car, while still in
contact with the chasis, then the current would use you as the
better route to ground. That would be bad.
BUT if you can jump out BEING SURE YOUR TOTALLY IN THE AIR then
you can exit the car with no problems.
But to take that flying leap... Current jumps at the rate of
about 10,000 volts per inch. You better clear the car
completely, *and* all the wet pavement, by quite a bit... This
is totally not recommended. The best thing to do is just sit
tight until the power is turned off.
Yeeeeesh. Personally, I think I'll just stay indoors during a
thunder-and-lightning storm! :-O
Hiding under the bed might offer even more "security."
