We totally should. I mean it isn't even controversial idea: https://en.wikipedia.org/wiki/Vision_Zero . If we start with "all traffic related deaths are excessive" then trying to get rid of them in any way possible is only natural. Shame that 2nd amendment fans will be against any requirements for gun owners, event if they are similar to European commercial drivers tests.
Psychological test before buying a gun? What a heresy.
Haha, sure. One, the tyrannical government is taking roots day by day and no one does shit. Two, even in this fantasy world where half the people wasn't on board with the destruction of our democracy, if the people as a whole were to take arms, they'd be going after a professional army whose budget is many orders of magnitude higher than this citizens militia's.
History shows that an underfunded militia can still tie down or even outlast the U.S. military in a guerrilla context - Vietnam, Afghanistan, and Iraq are all examples.
