The National Highway Traffic Safety Administration said on Tuesday it is withdrawing a 2012 Obama administration proposal to demand event data recorders in all new cars and trucks since it states automakers have voluntarily installed the devices in nearly all vehicles.

The agency proposed requiring the devices, sometimes called”black boxes” in most vehicles, but had not finalized it.

The head of consumer advocacy group Center for Auto Safety questioned the operator’s move. In an email, manager Jason Levine said the decision to withdraw the proposal”seems particularly problematic as the demand for uniform crash data elements to assist crash investigators only increases with each iteration of advanced security technology.”

NHTSA couldn’t immediately be reached for additional comment.

The agency also proposed in December 2012 requiring the capture of safety-related data in the seconds before and during a motor vehicle crash. In 2006, NHTSA necessitated the selection of certain data such as vehicle speed, crash forces in the moment of impact, whether an air bag deployed or if the brakes were implemented in the moments before a crash and if seat belts were fastened.

NHTSA said in a statement that it was withdrawing the proposal since almost 100 percent of producers voluntarily equip vehicles using the devices.

The agency added it’s working with a proposal to update pre-crash recording requirements for event data recorders which was demanded by Congress at a 2015 law.

That law requires the agency to establish the”appropriate period” for vehicles to capture data to provide”accident investigators with vehicle-related information pertinent to accidents involving such vehicles.”

A 2014 congressional report said data in the devices can be used by law enforcement agencies to help determine why an accident occurred and can be used by automakers to understand vehicle performance in collision scenarios and by security officials to probe security problems.

The Trump government has vowed to eliminate what it rains unnecessary regulations.
