They are both holy cows, but very different holy cows.
In 2019 in the US, 20 people died in "school shooting deaths" meaning someone who was shot at a school of some kind
In Germany 0 people died in "school shooting deaths".
You are not seriously suggesting that the US does not have a gun problem?! Of course it has one. We can argue about how to solve it, but what you are doing is almost belittleing children who died like this.
This may be in part due to licensing requirements. I'm led to believe that in Germany you have to demonstrate that you have some skill at driving to receive a license, plus it's fairly expensive. In the US, it varies some by state, but a driver's license tends to be under $100 (most states I've had to worry about cost around $50 or less) and all you really need to demonstrate is ability to park, stop at a stop sign, maybe turn around in a box, and use your turn signal. Sometimes there's a road test where you might have to drive around the block. Also, I'm not sure if Germany does it, but I'm not aware of any state in the US that requires you to test ever again except maybe if you lost your license. But then, I've lost my license a few times for various reasons, and only once when I was in Texas did I have to take the written test to get it back.
But there is a long lasting ongoing discussion if license renewals should be introduced, at least for people above a certain age limit (70 or 80).
Considering German drivers consider themselves particularly careful and attentive etc, that's unimpressive.
