God, I hate this kind of news, it feels like it pops up every few months.
Germany issuing travel advisories is nothing newsworthy! They exist for basically every country (see https://www.auswaertiges-amt.de/de/reiseundsicherheit/reise-und-sicherheitshinweise, German only) and are updated regularly. The only thing that would be noteworthy if the US suddenly appeared on the travel warnings page: https://www.auswaertiges-amt.de/de/reiseundsicherheit/10-2-8reisewarnungen, on which the only surprising country is Japan, and the warning refers to the areas still affected by the Fukushima nuclear reactor accident.
As another example, Canada which is a very safe country, also has formally issued travel advisories: https://www.auswaertiges-amt.de/de/service/laender/kanada-node/kanadasicherheit-204874 though they basically only say “don’t worry”. But issuing an advisory is not what people might think it is.
I know you’re joking, but this is for when you have a reboarder type baby car seat in the passenger seat, in that case the airbag must be deactivated
