1910 Walden W. Shaw and John D. Hertz formed the Walden W. Shaw Livery Company, which later became the Yellow Cab Company. The first yellow cab hit the streets in 1915, and its distinctive colour became the company’s trademark. The company was also the first to use automatic windshield wipers, ultrahigh frequency two-way radios, and passenger seat belts

My goodness. They did a lot for car driving safety. I wonder if Hertz had anything to do with Hertz Car Rental. Couldn't be a coincidence. Or could it?
