No, it wouldn't, because that's not what we're discussing. The discussion was danger one vehicle poses to the other, and the only significant cause for bike fatalities is car accidents - there are no chasms to fall in in the flattest country in the world, and the speed at which one travels on a bike is much slower so much less likely to be fatal in case of a crash with a stationary object. So this is a very real metric of how dangerous bikes are to cars and vice versa.

EDIT: And even then it's skewed in favour of the car, because for cars the fatality rate is more likely due to crashes with other cars.
