Ok im having a really annoying time with my father here. Now statistically, you are much more likely to get in an accident in a car then in a small airplane per mile traveled. Now my father thinks that its better to say that its more dangerous to have a small airplane since you are more likely to get in an accident based on the number of times you start your engine. Now i say, the statistic should be based on miles, he says on startup and I'm almost positive my statistic is the correct basis since people's accidents occur while driving and not when they start-up their car. Extrapolate the idea out and someone who drives 100000 in one trip has a faaaaaaaaaaaaar larger chance of getting in an accident then someone who turns his car on once and drives across the street and back. Now i want to really verify that my statistical basis is correct... and if it is, how can you convince someone that you are right. This may be more reasonably put in the GD section.
