"Regulator Proposes Mandatory Anti-Drunk Driving Tech in Vehicles"

The National Highway Traffic Safety Administration (NHTSA) is seeking input on technologies that can be built into cars to prevent or mitigate drunk driving, as there are currently no commercially available options. NHTSA evaluated 331 driver monitoring systems but found none that can properly identify alcohol impairment. While blood alcohol detection technology is considered a more viable near-term solution, it is considered "active" and goes against the law's passive requirement. NHTSA is exploring touch-based methods, such as embedding a touch sensor in the push-to-start button, which could be considered passive. However, there are various challenges and questions to address, including ensuring driver engagement and handling emergency situations. The final regulation must be standardized by November 2024.
