- They'll soon be required in every new car: Last year's Infrastructure Investment and Jobs Act gave the federal government until November 2024 to create a rule guiding how these drunk driving prevention systems will be implemented.- Unlike existing breathalyzers, which require a person to blow forcefully into a mouthpiece, the new system automatically determines a driver's alcohol concentration with a sensor in the door or steering column that captures a person's breath.- The system can distinguish between the breath of drivers and passengers, and parents can program it for zero-tolerance to keep their underage children from driving after consuming any alcohol.Where it stands: A Swedish company, Senseair, has licensed the first iteration of the breath sensor technology, and could bring it to market as early as next year, Robert Strassburger, president and CEO of the Automotive Coalition for Traffic Safety, tells Axios.- And they're refining the breath sensor to eliminate "interference" from benign substances with alcohol, such as hand sanitizer, certain vaping liquids and even a monk fruit sweetener found in some energy bars."
