A closer look at the text revealed it is true the federal government gave itself three years to establish a rule that would require new cars to be “equipped with advanced drunk and impaired driving prevention technology.” However, what that new technology will entail had yet to be determined. Furthermore, a host of factors may extend the 2024 deadline for the new rule. Lastly, there is no mention of a “kill switch” that law enforcement could use to “shut your car off.”
