- The rating of transportation system safety by fatalities per
- passenger mile always struck me as bogus. Subjectively, what
- matters is the probability of exit. That is if I climb in and
- close the door, what are my chances of opening the door and
- climbing out. By this measure the STS is only about 1 in 50,
- although it probably isn't as dangerous as, say, a fighter in combat.
-
- Does anyone have any idea how various means of transport rate
- according to probability of exit. Is the private car better than
- a commerical airliner? {Lots of safe little trips would up the
- exit probability.}
