Some of these fall into the old correlation-causation trap. People who wear leather jackets are more likely to get into motorcycle accidents, but putting on a jacket alone doesn't change your likelihood of an accident.

There's also contexts missing from many of the other statistics: where you drive and the kind of car affects the mortality rate of driving, for instance.

The micromort is still a useful concept in specific controlled conditions (radiation exposure), or as a first approximation of quantifying risk, but the general statistics should definitely be taken with many grains of salt.
