	The electric field created by a power line would be much
stronger than that created by a mobile phone.  Also, the lower
frequency put out by power lines is more difficult to shield against
than cell phone frequencies.  Therefore, if your cell phone could
damage your circuit, you should only use it in areas that do not have
power lines or electrical equipment (the Outback?).

From now on I will stop my car 100 ft from the pumps and push it the rest of
the way.   And I will wear an ESD wrist strap grounded to the pump and
another strap connecting the car chassis to the pump before starting to add
the fuel.

Then by the same reason they need to ban keyfobs.

Much further away from the device that can be damaged.

They do when its close enough.

Aircraft radar system particularly can blow the shit out of the
front end of other systems if they are activated on the ground.
