The point you're missing is that the risk-taking & skill-honing that aggressive drivers perform is being done on public roads with other drivers who just want to commute safely.

Your arguments are about pilots training in controlled conditions that don't put others at unnecessary, non-consensual risk.

I am a GA pilot. I also do sim-based training rather than going out and doing risky in-airplane training in order to be safer. (There are some things that we do in airplane because it’s the most effective way available, but most of the really risky items we also do only in the sim.)

I confined my upthread answer to airline pilots because that’s what’s familiar and relevant to most readers and seems most directly relevant to risk-reduction for passengers/non-participants. (We don’t do risky training exercises with pax on board either.)
