SACRAMENTO, Calif.
“Research has shown that this does have an impact in getting people to slow down, particularly since some people don’t realize how fast that their car is going,” said state Sen. Scott Wiener, a Democrat from San Francisco and the bill’s author. While the goal is to reduce traffic deaths, the legislation would likely impact all new car sales in the U.S. That’s because California’s auto market is so large that car makers would likely just make all of their vehicles comply with the state’s law.for decades, rules that more than a dozen other states have also adopted.
