I think that the practical possibility of a mobile phone causing an
explosion is somewhere on the region of zero

This sort of discussion always reminds me of a talk on risk I remember
from years back. "Are you willing to take a risk if the odds are
1000 to 1?" Most people would say "yes." "OK here is a jar with 1000
smarties in it, plus one that has cyanide in it, would you like to
take one?" answer was normally "no"

Surely that depends on how much you like Smarties? I don't eat sweets,
biscuits or chocolate, neither do I take sugar simply because I can't stand
the taste of sweet things. I wouldn't eat a Smartie if you paid me [1].

With mobile phones and the hazard on garage forecourts the bigger risk
is if they are dropped and break in a way to cause sparks or a fire in
the phone, very remote but possible, I have had a portable radio,
walkie talkie, catch fire due to a fault and would not have wanted to
be near any explosive gas mix.

So what about the alternator, distributor, HT leads etc in a car/motorbike
engine?

[1] OK, it would depend on how much :-)
