Which invention is Mary Anderson most famous for contributing to vehicle safety?

Mary Anderson is most renowned for her invention of the windscreen wiper, which has become an essential feature in vehicle safety. When she noticed that streetcar operators had difficulty seeing during rainstorms because of the lack of effective means to clear water from the windshields, she designed a device that would allow drivers to clear their view with ease. This innovation significantly improved visibility and, consequently, safety for drivers and passengers in vehicles.

While hybrid engines, seat belts, and airbags also play critical roles in vehicle safety, they were developed by different inventors or companies and are not attributed to Mary Anderson. The inclusion of her invention in the context of vehicle safety emphasizes how addressing visibility issues can directly impact the reduction of accidents and enhance driving conditions.
