Mercedes-Benz wants to introduce flashing brake lights to prevent deadly rear-end crashes. Since rear-end accidents claim 1,600 lives a year in the United States, it seemed like a bright idea. But federal regulators have determined that the solution is not right for the United States, even though safety officials in the European Union like it.
Still, automakers and suppliers should continue to develop ideas that can save lives, rather than passively wait for a mandate from the National Highway Traffic Safety Administration or Congress. And NHTSA should always look at new ways to make cars safer, even if the ideas originate with industry.
