Because it would save lives (boldface mine):
New cars would be required to have technology to stop drunk people from driving under a mandate Congress approved as part of the sweeping infrastructure bill — a step that could significantly reduce one of the leading causes of crash-related deaths.
More than 10,000 people died in crashes involving an alcohol-impaired driver in 2019, according to the National Highway Traffic Safety Administration. Campaigners against drunken driving say the new technology would bring that number down dramatically — and that it’s needed at a time when once-declining death rates have plateaued in the past decade.
“This technology will essentially eliminate drunken driving,” said Alex Otte, president of Mothers Against Drunk Driving.
The mandate is among several road-safety provisions in the infrastructure bill. It also calls on NHTSA to require automatic braking for cars and the largest trucks, for a revamp of vehicle safety ratings and requiring in-vehicle alerts to help stop children from being left in hot cars. The bill also seeks to address the design of roads, providing money for designs that prioritize the safety of pedestrians and cyclists.
Of the measures in the bill, the drunken driving technology provision could have the greatest potential to save lives.
A recent study by the Insurance Institute for Highway Safety concluded the technology could reduce deaths by 9,400 people a year if widely deployed. Such a reduction would likely take years to materialize, but under a timeline set out by lawmakers, the technology could be required in new vehicles as soon as 2026.
They’ll portray it as an attempt to tell Americans when and how to drive, because freedom. Sure, it’s popular, but so are a bunch of other issues they screech about, and since the party has become an appendix to the anti-vaccination movement, don’t assume they won’t sink to this level, as stupid as it would be.
