The US banned leaded gasoline (at a federal level, states had banned it since the 1920s) in 1996. Austria was the first European country to ban leaded gas, and they did it in 1993. The first country world wide to ban leaded gas was Japan and they did it in 1986.
And the EU didn't ban leaded gas as a whole until 2000
And its still not entirely banned in the US, AVGAS for small planes is a "low" lead fuel that still contains a decent amount of lead.
Avgas is the last hold out for that, yes. But piston powered airplanes are becoming rarer and rarer.
True, though they are more common than you think, there's still thousands of flights daily across the U.S. and where I live its the only mode of transportation in/out of a lot of communities. On thing that's common though is a mod to allow the planes to run on car gas, 85 or better octane. That helps us and them (much cheaper) and a lot of modern small aircraft are moving to diesel piston engines like the Thielert engines.
Dieselpunk all the way!
