Yes, they'd also like to make you think that cell phones will cause and
explosion while filling your tank. I'm thinking since a cell phone is a
duplex transceiver there is no antenna switching, no relays to arc so what
would cause an explosion? A watt or so of rf, not in my life!

A nitpick that reinforces your point, cell phones are normally .6
watts max. Most automatically reduce power with good reception, and
furthermore digital phones have a small duty cycle (only transmit
very short bursts several times a second). I think the old car
phones used 3w.

The funny thing about some (all? my old Motorola at least) cell
phones is the moment when someone calls you and your cell phone rings
or vibrates, it also transmits peak power (an electronic "I'm right
here!!!" to the network?). So do we put polite signs next to gas
pumps for all to turn off their phones? Heh, people can't even get
that right in a movie theater, church, court, on an airline...

To paraphrase what you said, hahahaha.

Funny the thread should turn this way, and on the topic of aviation,
a few military fields I've stopped at over the last year now have a
rule against using cell phones close to the fuel truck (filled with
JP-8 nonetheless). Most squadrons and/or bases have restrictions on
hot refueling- turn off transmitters like transponders, radar
altimeters, don't make radio transmissions, but cell phones and cold
refueling is taking it a bit far.
