IIHS to develop nighttime AEB evaluation after study finds emergency braking systems make no difference in the dark
A study by the Insurance Institute for Highway Safety (IIHS) found that pedestrian crash rates were lower when vehicles were equipped with pedestrian automatic emergency braking (AEB) systems. However, the agency’s study also revealed that AEB systems practically made no difference in pedestrian crashes that occurred at night.
“This is the first real-world study of pedestrian AEB to cover a broad range of manufacturers, and it proves the technology is eliminating crashes,” says Jessica Cicchino, IIHS vice president of research. “Unfortunately, it also shows these systems are much less effective in the dark, where three-quarters of fatal pedestrian crashes happen.”
The AEB System Study
Cicchino, the IIHS study’s author, looked at nearly 1,500 police-reported crashes involving 2017-2020 model-year vehicles from different manufacturers to determine the impact AEB systems made in pedestrian crashes. The study accounts for the quality of the vehicle’s headlights, along with the driver’s age, gender, and other demographic factors.
The study found that pedestrian crash rates of all severities were 27% lower when vehicles were equipped with AEB systems. Injury crash rates were 30% lower. However, the study also found that AEB systems made no difference in tests conducted in “unlighted areas.”
Cicchino made the discovery among a subset of 650 crashes with more detailed information about lighting conditions, speed limit, and crash configuration. The more detailed data revealed that AEB systems reduced the odds of pedestrian crashes by 32% in daylight and 33% in areas with artificial lighting, during dusk or dawn and nighttime.
Nighttime AEB Evaluation Tests
The manager of active safety testing at IIHS, David Taylor, and his team have already conducted some research tests to design the planned nighttime pedestrian AEB evaluation. Eight small SUVs from eight different manufacturers were put through the standard vehicle-to-pedestrian evaluation in complete darkness.
IIHS tested a 2019 Subaru Forester, 2019 Volvo XC40, 2020 Honda CR-V, 2020 Hyundai Venue, 2021 Chevrolet Trailblazer, 2021 Ford Bronco Sport, 2021 Toyota C-HR, and 2022 Volkswagen Taos. Each vehicle went through the evaluation twice.
Current Vehicle-to-Pedestrian Evaluation
The IIHS vehicle-to-pedestrian evaluation is a 6-point scale, as seen below. The test consists of several scenarios where adult and child-like dummies “walk” perpendicular or parallel to the vehicle at varying speeds. Total points for perpendicular scenarios are weighted at 70%, while points from the parallel scenario are weighted at 30%.
During five test runs, vehicles were awarded points based on their average speed reduction. An additional point is awarded in the 37 mph parallel scenario to cars that provide the driver a warning at least 2.1 seconds before impact.
Nighttime AEB Evaluation Test Results
The vehicles the IIHS chose for the test included cars that used single cameras, dual cameras, single camera and radar, and radar only configurations. The test also had vehicles that already took the vehicle-to-pedestrian front crash prevention evaluation and earned ratings ranging from superior, advanced, and basic.
Except for the radar-only Taos, all the vehicles’ performances declined in the dark, dropping some of their ratings from superior to advanced when using high beams and superior to basic when using low beams. The Taos received essentially the same nighttime tests scores compared to daytime evaluations. However, the IIHS noted that the Taos was also the worst performer during the daytime tests.
The best performers in the nighttime tests were the 2021 Ford Bronco Sport and 2021 Toyota C-HR. Both vehicles use a combination of cameras and radar.
“The better-performing systems are too new to be included in our study of real-world crashes,” noted Aylor. “This may indicate that some manufacturers are already improving the nighttime performance of their pedestrian AEB systems.”

Tesla CEO Elon Musk reveals new details about Robotaxi rollout
The first Tesla Robotaxi unit was spotted in Austin earlier today, and CEO Elon Musk is revealing some cool new details.

Tesla CEO Elon Musk has revealed new details about the company’s relatively imminent rollout of the Robotaxi platform as the suspected launch date of June 12 continues to near.
Earlier today, the first video showing the first driverless Tesla Robotaxi in Austin was shared on X, just a day after the City officially listed the company as an autonomous vehicle operator on its website. Tesla is listed as a company in the “Testing” phase.
🚨 BREAKING: The first Tesla Robotaxi has been spotted in Austin!
It’s has the word “Robotaxi” inscribed on the side, and it’s very clear that there is nobody in the driver’s seat.
It does appear that someone is in the passenger’s seat. https://t.co/6BdTfd4B8p pic.twitter.com/dygWCeQ5kZ

The initial details of the Robotaxi are being revealed by Musk, who is carefully releasing small tidbits that seem to show the capabilities of the entire Tesla fleet, and not necessarily just the vehicles that will be involved in the initial rollout in Austin.
First Tesla driverless robotaxi spotted in the wild in Austin, TX
His first tidbit is one that many Tesla owners and fans will already know: many Teslas are capable of this driveless performance, but Full Self-Driving is not yet refined to the point where the software is quite ready to handle it. Current versions are robust, but not prepared for driverless navigation. The hardware, however, will enable Teslas to be Robotaxis, even if they’re already purchased by owners:
These are unmodified Tesla cars coming straight from the factory, meaning that every Tesla coming out of our factories is capable of unsupervised self-driving! https://t.co/n94ln0Uas6

This is one of the biggest advantages Tesla has over other vehicle makers. Simply put, the Over-the-Air software updates that will roll out to FSD users will eventually make their cars into Robotaxis as well.
However, Musk shed some details on the version of FSD that is being run in these new Robotaxis that were spotted. Musk said that the version these Robotaxis are running is a new version, but will soon “merge to main branch.”
There is also an even newer version that has four times the parameters as this newer version that the test-stage Robotaxis are using, but Musk admits that this needs significant refinement before it is released to the public.
It’s a new version of software, but will merge to main branch soon.
We have a more advanced model in alpha stage that has ~4X the params, but still requires a lot of polishing.
That’s probably ready for deploy in a few months.

As of now, Tesla is simply teasing the actual launch date of the Robotaxi program, but Bloomberg reported earlier this month that it will occur on June 12.

First Tesla driverless robotaxi spotted in the wild in Austin, TX
The short clip suggests that Tesla may be ramping up its preparations for its robotaxi rollout in Austin.

A recent video posted on X has provided a first look at Tesla’s driverless robotaxi, which is expected to be deployed in Austin, Texas, this month. The vehicle was a new Tesla Model Y, which was followed by what appeared to be a manned chase car.
The short clip suggests that Tesla may be ramping up its preparations for its robotaxi rollout in Austin.
The First Robotaxi Sighting
It was evident from the short clip that the Tesla robotaxi was operating completely driverless. In the video, which was posted on X by @TerrapinTerpene, the driverless Tesla could be seen confidently making a turn. The vehicle looked and behaved like any other car on the road, save for the fact that there was no one in the driver’s seat.
Interestingly enough, the short video also provided a teaser on where Tesla will place its “robotaxi” logo on its self-driving cars. Based on the video, the robotaxis’ logo will be tastefully placed on the front doors, making the vehicles look sleek and clean.
Initial Rollout Imminent
Recent reports have suggested that Tesla is already starting the testing phase of its robotaxi service in Austin, Texas. Expectations are also high that Tesla’s initial fleet of self-driving vehicles will be utilizing a lot of teleoperation to ensure that they operate as safely as possible.
Updates to Austin’s official website recently have hinted at Tesla’s robotaxi launch. Just this Monday, Tesla was listed as an autonomous vehicle (AV) operator on Austin’s official Department of Motor Vehicles (DMV). Other AV operators listed on the site are Waymo and Zoox, among others.
Elon Musk, for his part, has noted that by the end of June, the public in Austin should be ready to take rides in Tesla robotaxis without an invitation. He also noted in late May that Tesla has been busy testing driverless cars on Austin’s city streets without any incidents.

Tesla Model Y proudly takes its place as China’s best-selling SUV in May
The Model Y edged out competitors like the BYD Song Plus.

The Tesla Model Y claimed its position as China’s best-selling SUV in May, with 24,770 units registered, according to insurance data from China EV DataTracker.
The Model Y edged out competitors like the BYD Song Plus, which recorded 24,240 registrations, as well as Geely’s gasoline-powered Xingyue L, which took third place with 21,014 units registered, as noted in Car News China report.
Return To The Top
The Model Y’s return to the top of China’s SUV market follows a second-place finish in April, when it trailed the BYD Song Plus by just 684 units. Tesla China had 19,984 new Model Y registrations in April, while BYD had 20,668 registrations for the Song Plus.
For the first five months of 2025, Tesla sold 126,643 Model Ys in China, outpacing the Song Plus at 110,551 units and BYD’s Song Pro at 80,245 units. This is quite impressive as the new Tesla Model Y is still a premium vehicle that is significantly more expensive than a good number of its competitors.
Year-Over-Year Challenges
Despite its SUV crown, Tesla’s year-over-year performance in China is still seeing headwinds. May sales totaled 38,588 units, a 30% year-over-year decline. From January to May, Tesla delivered 201,926 vehicles in China, a 7.8% drop year-over-year. These drops, however, are notably affected by the company’s changeover to the new Model Y in the first quarter.
Exports from Tesla’s Shanghai Gigafactory also fell, with 90,949 vehicles being shipped from January to May 2025. This represents a decline of 33.4% year-over-year, though May exports rose 33% to 23,074 units.
China’s electric vehicle market, meanwhile, showed robust growth. Total NEV sales, which includes battery electric vehicles (BEVs) and plug-in hybrids (PHEVs), reached 1,021,000 units in May, up 28% year-over-year. BEV sales alone hit 607,000 units, a 22.4% increase.
Considering the fact that China’s BEV market is extremely competitive, the Tesla Model Y’s rise to the top of the country’s SUV rankings is extremely impressive.
