I feel like the axes need better labeling. Putting the labels on the negative is confusing.

Fun idea, bad execution. Do it again with text that isn't for ants, axis with a single arrow, and labels on the positive side, and a legible font.

Idk about the bikes, downhill mountain biking is very safe as long as you don't crash

This stemmed from me joking with a friend that it is unfortunate that flying is so safe because I always want to die when I'm on plane.

So where do we put motorcycle riders? Is there a suicidal category on this graph?

Flying is not low likelihood of death. Commercial passenger aviation is.

Private planes crash and kill their occupants fairly often.

Commercial flight is safe just because there are so many regulations that are (were?) strictly followed. If you really wanted to reduce auto deaths, you could absolutely regulate it down to the same risk as commercial aviation, but that would nerf the purpose of a car to the point that no one would actually use them.

Broadly speaking, the way regulations are written is according to our appetite for risk of death in that medium. Modes where you have some appearance of like cars and bikes see high acceptance of risk while modes where you are strictly "along for the ride" see low acceptance.

The fact that this could pretty much be a pcm meme too makes it top notch!

Exercise is good for mental wellbeing though

GTFO with your antibike propaganda.
