It's silly to worry about cell phones when every car that drives in
has a high-voltage ignition system under the hood, 12V spark-producing
switches in the door frames, and a hot catalytic converter underneath
the car.

The RF/electrical bit seems like a red herring to me, but I suppose it
would be better to give full attention to the flammable liquid you're
pumping rather than a telephone conversation.
