<big>Not necessarily. Rewind this thread to the video of the SUV being
hit by lightning while on a highway and while surrounded by telephone
and hydro poles.<br>
Granted, this was on a rural highway and was not in an urban
environment. But the "lumpiness" of the charges in the atmosphere and
ground will conspire to go against any of the common "rules of thumb".
Rural or Urban.<br>
<br>
And while we are talking about lightning myths I will stir the pot with
this left over from the same video: <br>
With respect to lightning, the insulation provided by the tires on the
SUV is inconsequential. <br>
At the voltages involved everything becomes a conductor, tires included.<br>
<br>
The tires on the SUV may provide some protection for low to medium
voltages up to 13.8 kVac maybe more. As with lightning, the insulation
may break down or suffer from creep, with higher voltages.<br>
<br>
There is a section on antennas in the following article:<br>
