Today, even in USA, one has to pass a test to get a driver license. Why not for firearms as well?\n\n\nBecause driving is not a constitutional right that "shall not be infringed". Some jurisdictions, New York State and especially New York City, do require licenses for gun possession, and they charge fees for the licenses, but the Supreme Court has wiggled out of ruling on these licenses. So far they have not ruled these licenses unconstitutional, but I suspect that's coming soon with Trump's appointees. Anyway, with ~400 million civilian guns in the US, and record numbers being sold since Biden was elected, controls at this point, IMO, are more for a feel-good discussion than results. The situation looks hopeless.
