Well y'know I hadn't really thought of that. If there was a leak into a
small space like the cabin of a car it could fill it up quite quickly and
then a spark from any one of a gazillion things...
It's not like it's on the downside of a regulator like in an RV... in fact
it'd be the opposite.
Like John, I had put at least part of it down to politics... and I agree
with you about the Ford.

Robert
