Thanks for all the input. Having thought about it the first thing to do is to decide what figure most accurately represents "most dangerous form of transport". For me it would be number of fatalities to number of hours exposure (and let's keep this in the civilian world). Anything else i.e. journeys made or distance travelled is not going to give as clear a picture when helicopters are involved. And I do appreciate there are certain types of civillian flying more dangerous than others but lets bung 'em all in together.. So now that has been decided you simply (yeah right) get hold of the number of hours driven, pedalled, riden etc. and compare. Anyone?! Didn't think so...
Actually having thought about it some more there are so many variables,
Head Turner I think you are right - statistics can be used to present anything in any light you want. Listen to two arguing politicians and they will both have numbers that sing and dance for them on the same subject...
Bottom line - can of worms.
Oh well.
Cheers
