I don’t get it. Because it “hurts” when you have an accident? Hertz is a normal German name, like Heinrich Hertz, for example. And I just read up, the guy who bought the original car rental company from another guy in the early 1900s was John D. Hertz. Whose birth name was Sándor Herz, and his family came from Austria-Hungary. Herz means heart in German.
