Elon Musk’s Push to Expand Tesla’s Driver Assistance to Cities Rankles a Top Safety Authority

Excerpt:

Tesla Inc. is readying a major upgrade of its driver-assistance software but the top federal crash investigator says the move might be premature.

Chief Executive Elon Musk said last week that drivers would soon be able to request an enhanced version of what Tesla calls its “Full Self-Driving Capability.” The upgrade is expected to add a feature intended to help vehicles navigate cities, expanding the suite of driver-assistance tools that had been designed mainly for highways.

Despite its name, Full Self-Driving doesn’t make cars fully autonomous, and Tesla instructs drivers to remain alert, with their hands on the wheel.

Jennifer Homendy, the new head of the National Transportation Safety Board, said Tesla shouldn’t roll out the city-driving tool before addressing what the agency views as safety deficiencies in the company’s technology. The NTSB, which investigates crashes and issues safety recommendations though it has no regulatory authority, has urged Tesla to clamp down on how drivers are able to use the company’s driver-assistance tools.

Why Are Pedestrian Deaths at Epidemic Levels?

Excerpt:

For years, transportation consultant and writer Angie Schmitt has tried to pick apart why it works that way and how the U.S. could become a less car-centric and less dangerous place. In 2020 she published Right of Way: Race, Class, and the Silent Epidemic of Pedestrian Deaths in America, an examination of the toll that the nation’s auto-centric infrastructure takes on those who are not encased in steel and glass when they travel.

Schmitt found that even as reported rates of walking among Americans have been on the decline, pedestrian deaths have surged in recent years. Between 2009 and 2019, total driving miles increased by 10 percent but pedestrian deaths increased by 50 percent. In Europe, by contrast, they fell by 36 percent over the last decade. Since then, the U.S. toll has only grown worse.

…..

Schmitt: Design is important, but I think we also need to change cars. We can go a lot of the way there just with better vehicle safety regulations. The RAND Corporation estimated we could be saving at least 10,000 lives a year, maybe 20,000, if we were requiring some existing vehicle technologies in all cars like automatic emergency braking. Or blind spot detection and alcohol ignition interlocks. A combination of things like that already exists, and we could save tens of thousands of lives. We’re just not doing it. There’s been so little attention paid, it’s been hard to generate political will.

Abstract:

Machine learning methods have garnered increasing interest among actuaries in recent years. However, their adoption by practitioners has been limited, partly due to the lack of transparency of these methods, as compared to generalized linear models. In this paper, we discuss the need for model interpretability in property & casualty insurance ratemaking, propose a framework for explaining models, and present a case study to illustrate the framework.

Excerpt:

The NEMSIS data include metrics on crash severity. For people treated at the scenes of motor vehicle crashes, EMS professionals use an injury scoring system called the Revised Trauma Score (RTS) to determine the level of care needed to save the lives of the injured. Under
RTS, patients who present with a probability of survival of 36.1% or less are considered severely injured and are often transported to Level 1 or Level 2 trauma centers that provide higher levels of critical care to the most severely injured. Figure 4 shows the percentage of
patients in crashes whose probability of survival was in this range for 2019 and 2020. Beginning in Week 12 of 2020, the percentage of those injured with a probability of survival of 36.1% or less never dropped below 1%, suggesting an increase in the severity of crashes.

Excerpt:

Total fatality rate per 100 million VMT [vehicle miles traveled] is broken down by roadway function class: rural versus urban interstate, arterial, local/collector/street. The results shown in Figure 2 indicate that the increased trend of the total fatality rate per 100 million VMT from March to December 2020, was mainly driven by the fatality rate per 100 million VMT on the rural local/collector/street, rural and urban arterial roadways.

Excerpt:

Preliminary finding show that traffic fatalities rose in most major categories over 2019: 

Passenger vehicle occupants (23,395, up 5%)

Pedestrians (6,205, flat from 2019)

Motorcyclists (5,015, up 9%)

Pedalcyclists (people on bikes) (846, up 5%)

Crash factors and demographics reviewed by NHTSA that showed the largest increases in 2020 as compared to 2019 included: 

non-Hispanic Black people (up 23%); 

occupant ejection (up 20%);

unrestrained occupants of passenger vehicles (up 15%);

on urban interstates (up 15%);

on urban local/collector roads (up 12%);

in speeding-related crashes (up 11%);

on rural local/collector roads (up 11%); 

during nighttime (up 11%); 

during the weekend (up 9%); 

in rollover crashes (up 9%); 

in single-vehicle crashes (up 9%) and; 

in police-reported alcohol involvement crashes (up 9%).

There are a few categories that are projected to have decreases in fatalities in 2020. Fatalities in crashes involving a large truck (commercial or non-commercial use) are projected to decline marginally (down 2%).  Fatalities among older persons (65+ years of age) are projected to decline by about 9 percent.

We need to design distrust into AI systems to make them safer

Excerpt:

Since that experiment, have you seen this phenomenon replicated in the real world?

Every time I see a Tesla accident. Especially the earlier ones. I was like, “Yep, there it is.” People are trusting these systems too much. And I remember after the very first one, what did they do? They were like, now you’re required to hold the steering wheel for something like five-second increments. If you don’t have your hand on the wheel, the system will deactivate.

But, you know, they never came and talked to me or my group, because that’s not going to work. And why that doesn’t work is because it’s very easy to game the system. If you’re looking at your cell phone and then you hear the beep, you just put your hand up, right? It’s subconscious. You’re still not paying attention. And it’s because you think the system’s okay and that you can still do whatever it was you were doing—reading a book, watching TV, or looking at your phone. So it doesn’t work because they did not increase the level of risk or uncertainty, or disbelief, or mistrust. They didn’t increase that enough for someone to re-engage.

Motor Vehicle Deaths in 2020 Estimated to be Highest in 13 Years, Despite Dramatic Drops in Miles Driven

Mary Pat Campbell

Link: https://www.nsc.org/newsroom/motor-vehicle-deaths-2020-estimated-to-be-highest

Excerpt:

For the first time since 2007, preliminary data from the National Safety Council show that as many as 42,060 people are estimated to have died in motor vehicle crashes in 2020. That marks an 8% increase over 2019 in a year where people drove significantly less frequently because of the pandemic. The preliminary estimated rate of death on the roads last year spiked 24% over the previous 12-month period, despite miles driven dropping 13%. The increase in the rate of death is the highest estimated year-over-year jump that NSC has calculated since 1924 – 96 years. It underscores the nation’s persistent failure to prioritize safety on the roads, which became emptier but far more deadly.  

An estimated 4.8 million additional roadway users were seriously injured in crashes in 2020, and the estimated cost to society was $474 billion. With the alarming picture painted by these data, NSC is urging President Joe Biden and Transportation Secretary Pete Buttigieg to commit to zero roadway deaths by 2050 – a call NSC and more than 1,500 other organizations and individuals made in January in a letter to the new administration.

Bricks Without Straw?

Mary Pat Campbell

Link: https://www.rstreet.org/2021/03/30/bricks-without-straw/

Excerpt:

Credit analytics firm FICO posits that the reason for the correlation of credit history and claim probability is that “individuals who closely and cautiously monitor and manage their finances tend to also take better care of their cars and homes and are, generally, more diligent in their risk management habits.” Because such individuals are found across demographic classifications, the discrimination argument becomes hard to uphold.

If insurers find that credit scores have bearing on accident propensity, insurers should be allowed to use them. Preventing insurers from deploying basic tools required to generate appropriate risk-adjusted prices leads to mispricing of risk, harming insurance buyers as well as insurers. What is more, such deprivation leads to unintended negative consequences—an unfair socialization of risk, leaving customers either overcharged or undercharged. Executive fiat prohibiting insurers from accessing the tools of their trade is tantamount to Pharaoh ordering the Israelites of old to make bricks without straw. Bad business, bad policy.

Excerpt:

The National Safety Council (NSC) estimate of total motor-vehicle deaths for 2020 is 42,060, up 8% from 39,107 in 2019. The estimated annual population death rate is 12.8 deaths per 100,000 population, up from 11.9 in 2019. The estimated mileage death rate is 1.49 deaths per 100 million vehicle miles traveled, up 24% from 1.20 in 2019. Estimated vehicle miles traveled for 2020 indicate over a 13% decrease compared to 2019, from 3,260 billion to 2,830 billion.

A medically consulted injury is an injury serious enough that a medical professional was consulted. Based on the current medically consulted injury-to-death ratio of 114:1, and rounded to the nearest thousand, the estimated number of nonfatal medically consulted injuries resulting from crashes during in 2020 was 4,795,000.

The estimated cost of motor-vehicle deaths, injuries, and property damage in 2020 was $474.4 billion.
