Sadly, Chicago saw its first bike fatality of 2025 on Memorial Day, when a Hummer driver fatally struck Yader Castaneda, 18, while he was riding an electric Divvy bike-share cycle in the Loop.
According to the initial Chicago Police Department statement, on Monday, May 26, at around 4:53 a.m., Castaneda was cycling on Randolph Street. As he crossed Michigan Avenue, he was involved in a collision with the motorist, 65, whom the statement said was traveling "southbound, through a green light."
The bike rider was taken to Northwestern Hospital in critical condition, according to the CPD. He was pronounced dead and hour later. According to the Cook County medical examiner's office, he lived in southwest-suburban Plano.
The driver, who was uninjured, was charged with failure to reduce speed to prevent a crash, police said.

The Illinois Traffic Crash Report, completed by responding officers, provides more details about what reportedly happened. It states that when police arrived at the scene, Castaneda was lying in the street on Michigan receiving medical care from first responders.
Friends of Castaneda were on the scene, the crash report states. They told police they were also riding bikes at the time of the collision.
According to the report, a police observation device camera recorded the Hummer driver heading south on Michigan with a green light. As Castaneda entered the intersection, he "went against the traffic signal, traveling westbound on Randolph, and which time [the motorist] struck [Castaneda], causing [the cyclist] to eject out of the Divvy bike he was operating."
The report states that there was visible damage to the Hummer. The driver was taken to Northwestern for a DUI test, and results were pending.

According to an online obituary, Castaneda had recently graduated from Plano High School and worked as a "talented" barber at a shop in nearby Yorkville.
A Sun-Times article on the case by David Struett identifies the driver as Peter Aleck, a resident of southwest-suburban Frankfort who owns a plumbing company based in south-suburban Homewood. Aleck said he was on his way to a gym, and was the only motorist stopped at the traffic light on Randolph.
"[Castaneda] must have thought there was no one coming," the driver told Struett. "I must have been halfway through the intersection. I thought it was a car."
Although Aleck said he did not see the approaching cyclist, and the police report says he was "distracted," he told the Sun-Times that was not the case. He insisted that he was looking "straight ahead" before the collision. "It’s terrible," he said. "I feel really terrible about it."
Christina Whitehouse, founder of the civic tech platform Bike Lane Uprising, noted to Struett that while Randolph/Michigan is next to Millennium Park, with high bicycle and foot traffic, it's a hostile intersection for vulnerable road users. While Randolph has bike lanes heading to and from the lakefront trail, Michigan has ten mixed-traffic lanes. There's no crosswalk on the south leg of the intersection, which means people walking from the Chicago Cultural Center at the southwest corner to the park at the southeast corner must cross three streets instead of just one.

Here are a few more thoughts about this tragic case. Without assigning blame for the crash, if the police statement that Aleck had the green is accurate, that indicates that Castaneda made a mistake by disobeying his stoplight. The electrical assist for electric Divvy bikes tops off at 20 mph. Randolph rises from Michigan east to the former Millennium Park bike station, so the downhill slope may have contributed to Castaneda's speed. But even if it's true the cyclist made an error, he didn't deserve to pay for it with his life.
And it's clear responding officers also believed Aleck's behavior played a role in the death, since the report states that the driver was distracted, and he was charged for failure to reduce speed to prevent a crash. That indicates police felt he might have been able to avoid fatally striking Castaneda.

Moreover, Aleck was driving an SUV whose design greatly reduced the bike rider's chances of survival. Identified by the Sun-Times as a 2024 EV Hummer, it's one of the heaviest consumer automobiles currently on the market in the U.S. Its poor sight lines and wall-like front end may have also been contributing factors.
While the City of Chicago doesn't have the power to ban such vehicles, it does potentially have the ability to make driving them more expensive. Paris recently tripled the price of parking an SUV, and Washington D.C. charges their owners a premium for city stickers. That might make them less popular vehicles here, which could help reduce our city's crash fatality rate.
It goes without saying that everyone should travel safely and considerately, regardless of whether they're walking, biking, or driving, and without being distracted, intoxicated, or reckless. But it's also true that there's a big difference in how much responsibility you have to avoid killing other road users if you're operating a 70-pound e-Divvy versus a 9,063-pound Hummer.
