We also put lead in gasoline knowing damn well it would come out the tail pipes and people on the streets would have to breathe it. Several decades of leaded gasoline passed until someone developed an alternative to fix engine knocks. If that had never been invented we would still be pumping lead into our streets today as a "cost of life" or more realistically, a cost of doing business.

Cars still offgas other heavy metals (arsenic, cadmium, chromium, nickel), and rhe wear from their tires also distributes heavy metals. Tractors do the same in our fields and have for decades. It's not good. Instead of developing drones for the military, we should develop them for our food supply first.

Piston aircraft still use it. Which makes it doubly annoying when some tit in a cesna decides to circle around town at 1000'.
Not just making a noise, also cropdusting with TEL.

Luckily that is beginning to change. But it is crazy that it has taken so long to do.

There seems to be two octane ratings that now have an unleaded replacement. (I don't know how many there actually are in use.)
