I had a similar decision to make (pilot or motorbike) and the fact that 60%+ of aviation deaths are pilot error and something like 60%+ of motorcycle crashes are NOT the rider's fault - led me to be a pilot. At least then I can try to make good decisions, e.g, DO NOT FLY INTO WEATHER.

MC rider. Many accidents occur during the early years, particularly as the new rider gets comfortable. There's a transition period where your muscle memory kicks in for basic riding skills, but not developed enough to keep you out of trouble. It is an incredible feeling of false confidence that makes you feel invincible. It's possible to be 'smart' and reduce risk during this period, but I'm not advocating people generally go out and start riding either.

I’m also pretty sure that the deaths per mile traveled in personal aircraft are only about 2x higher than for automobiles, which the general population just accepts as a sane default without question.

This should also put personal aircraft far below motorcycles.

And a lot of the pilot deaths are not because of in-the-moment skill deficiencies.

Stick and rudder skills aren't that useful with fuel exhaustion and bad weather planning. It's much easier to stay safer in a plane vs motorcycle.

I wish people treated cars and motorcycles properly, especially in the US. Until then, no motorcycles for me either :(

The stakes get even higher if you fly a plane with your entire family in it. One bad error and you will almost certainly have killed them all.
