Mayor Wu wants car safety ratings to consider a car’s threat to pedestrians


Wu wrote a letter June 2 to the Countrywide Freeway Targeted visitors Basic safety Administration with tips for motor vehicle features she argues ought to be taken into account when issuing 5-star protection ratings.

The Countrywide Highway Visitors Security Administration (NHTSA) is considering having into account a car’s danger to individuals outside the house the auto in its safety rankings, and Boston Mayor Michelle Wu is urging it to make these variations.

In a letter to the NHTSA dated June 2, Wu argues that a new automobile should really not be in a position to obtain a five-star safety score from the NHTSA if it does not score very on pedestrian basic safety capabilities, these as driver guidance devices, immediate visibility, and speed assistance programs that limit unsafe speeds.

“In Boston, in which the the greater part of residents’ do the job journeys include walking for a part or all of their journey, we are grateful that NHTSA is discovering how to protect men and women outside of the automobile as well as inside of,” Wu wrote.

Wu’s letter is in reaction to a decision in early March by Transportation Secretary Pete Buttigieg to talk to for community input on the NHTSA’s proposals for updates to the 5-star safety rating procedure for new vehicles, referred to as the New Car Assessment Method, or NCAP. 

Amid those people proposals is the opportunity inclusion of advanced driver-support program (ADAS) features, these as computerized crisis braking, blind-location detection, and lane-hold aid, in its evaluation of a new car’s protection.

The proposal is notable due to the fact these options are mainly meant to protect the lives of men and women exterior of a auto. In the NHTSA’s 52-yr record, it has only at any time viewed as the basic safety of individuals within the car in its basic safety scores, according to avenue protection advocate website StreetsBlog.

In this way, StreetsBlog documented, in spite of pioneering vehicle safety with the development of the NHTSA, the United States has fallen at the rear of Europe. 

In 2010, the European Union launched new automobile protection specifications meant to minimize pedestrian fatalities and accidents. These principles termed for specifications this kind of as higher hoods to reduce head trauma and crash tests that assess front-conclude impacts with pedestrians.

In 2012, late customer advocate Clarence Ditlow told Automotive Information that he considered the NHTSA was hesitant to control on pedestrian safety mainly because it would have a significant effect on how automobiles glance.

StreetsBlog also noted that David Zuby, main analysis officer with the Insurance policy Institute for Highway Basic safety (IIHS), thinks just one cause the NHTSA could not want to think about pedestrian safety in its safety scores is that it could considerably lessen basic safety rankings for SUVs and decide on-up vans.

According to Statista, crossover-type SUVs and decide on-up vehicles had been the two most well-liked types of cars in the United States, making up about 46% and 18% of the current market share in 2021, respectively.

In her letter, Wu even cites a March 2022 report by the IIHS that concluded that “[Light truck vehicles, such as SUVs, pick-up trucks, and vans] ended up much more likely to be associated in sure pedestrian crash sorts, implying a perhaps problematic visibility of pedestrians around the entrance corners of these vehicles.”

StreetsBlog documented that this isn’t the very first time that the NHTSA has viewed as introducing pedestrian safety things to consider to its motor vehicle basic safety ratings.

In 2015, StreetsBlog wrote, the company wrote on its internet site that it was contemplating incorporating some of the worldwide pedestrian safety benchmarks into its auto basic safety ratings.

The adjust wouldn’t have required carmakers to change something about their autos, StreetsBlog wrote, but some pedestrian basic safety metrics would be deemed in the NHTSA scores, and automakers are remarkably inspired to rating perfectly on these rankings.

But, StreetsBlog wrote, this disappeared from the NHTSA’s internet site following President Donald Trump took office.

In her letter, Wu cites a statistic from the IIHS which suggests that even though pedestrian deaths decreased steadily nationwide involving 1975 and 2009, due to the fact that small level, they have increased by 59%.

Even though Wu clarifies that pedestrian deaths in Boston did not increase that significantly in the final 13 many years, she warns that pedestrian fatalities in Boston could improve in the coming many years as electrical autos carry heavier control weights and speedier acceleration to the city’s streets.

“The City of Boston is encouraged to see NHTSA take the critical phase of incorporating basic safety options that guard persons exterior of motor vehicles into NCAP. Even so, the proposed adjustments to the Application can go even more,” Wu wrote in her letter.

Wu’s suggestion to the NHTSA is straightforward: don’t make it possible for autos to be presented a large safety ranking except if they score extremely on pedestrian protection metrics. She also features a record of auto safety groups that she indicates they make vital for earning a higher safety ranking.

First of all, she writes, new cars should really have sufficient and trusted ADAS functions, this sort of as blind spot detection and intervention, lane keeping guidance, and automated emergency braking, to receive a superior protection score.

Secondly, Wu advises, security scores must consider into account the likelihood of a pedestrian dying or staying critically hurt in a crash.

Thirdly, she writes, basic safety scores ought to take into account the “direct vision” of a driver from the driver’s seat — i.e. what a driver can see without the need of mirrors, cameras, and sensors.

“Cameras, mirrors, sensors, and other ADAS features are not able to exchange the require for immediate sight,” she writes. “Large automobiles, these types of as SUVs, gentle vehicles, and significant vehicles, have big blind spots and visibility difficulties, which are straight connected to lessened protection and improves in fatalities.”

Lastly, Wu advises, new autos should have smart velocity assistance units that quickly restrict unsafe speeds if they are to receive a superior safety score.

“Vehicle pace plays a crucial part in figuring out the likelihood and severity of visitors crashes, accidents, and fatalities. Crashes are a lot more very likely to arise as a driver’s pace raises, as does the probability of a crash getting deadly,” she writes.

“Intelligent pace help (ISA) is a device verified to reduce velocity-related crashes and fatalities.”

General public comments on the proposals closed June 8, but those people worried about auto security can nonetheless write to the NHTSA with comments on its site.

“The City of Boston significantly appreciates NHTSA’s consideration of these reviews and ensuring that buyers have the essential information and facts essential to make selections,” Wu writes, ending her letter.

“…NHTSA can do extra to leverage NCAP and make sure shoppers have a complete understanding of car or truck security.”
