The Guardrail Guy Paused His ALPR Advocacy After Vandalism Hit Close To Home

Steve Eimers has built an audience of hundreds of thousands of followers across major social platforms including YouTube, TikTok and X, where he creates content under the public alias “The Guardrail Guy.” His work centers on highlighting dangerous installation flaws in roadside guardrails across the United States, a mission he took up after an unthinkable personal loss.

Eimers first began posting about guardrail safety in 2022, three years after his 17-year-old daughter Hannah was killed when a defective guardrail pierced through her car during a crash, instead of redirecting her vehicle back onto the road as it was designed to do. This past April, he expanded his roadside safety advocacy to cover another common U.S. road feature: automatic license plate readers, or ALPRs.

Sold by major industry vendors including Flock and Axon, ALPRs are mounted high-resolution cameras that collect vehicle travel data, which law enforcement uses to track people suspected of criminal activity. Eimers began raising alarms about the technology after concluding improper ALPR installations create severe crash risks for motorists. His core claims are that many ALPR units are mounted too close to existing guardrails, eroding their core safety function, or attached to existing road sign posts that rely on breakaway designs to absorb impact—modifications that disable that life-saving feature.

Eimers’ ALPR videos struck a major nerve with audiences, at a moment when the technology is already one of the most controversial tools in modern policing. Cities across the country already debate ALPRs’ supposed crime-fighting benefits against well-documented risks of privacy abuse and mass oversurveillance. While Eimers’ content focused exclusively on the crashworthiness of ALPR installations, many commenters framed the devices as an invasive expansion of government surveillance in local neighborhoods.

Most concerning to Eimers was a growing tide of calls for vandalism. He began seeing hundreds of comments urging people to destroy the cameras, with many angry that he had not damaged the units himself. Other commenters asked for the exact locations of the cameras he highlighted, falsely claimed the devices contained precious metals like gold, silver and copper, and shared specific step-by-step vandalism methods. One comment on a July 24 Eimers post, paired with a photo of a large pipe cutter, read: “Large diameter pipe cutter. Nice and quiet, cuts it like butter!!!!”

On July 22, Eimers shared what looked like a major win for his advocacy: Flock, the most recognizable ALPR brand in the U.S., had committed to conducting a nationwide audit of all its camera installations to address safety concerns. Flock CEO Garrett Langley even publicly quote-tweeted Eimers, calling him a “true American hero.”

The celebration ended just three days later. On July 25, Eimers says he was driving home with one of his daughters when he passed the local Flock camera he had highlighted in his recent posts. He was shocked to find the device severely damaged, he told WIRED, and it appeared to have been shot. A few miles down the road, he found a second Flock camera he had featured in a May TikTok that had sustained nearly identical damage.

In response, Eimers made the decision to halt all ALPR-related advocacy work indefinitely. “Seeing those damaged cameras left me feeling a little bit shell-shocked,” he told WIRED. He added that the escalation of anger toward ALPR vendors is unlike anything he ever experienced during his years of guardrail advocacy. “I just haven't seen or experienced what I've experienced over the last few months with the escalation ever with any of my guardrail advocacy work,” he said, adding he does not want to “feed the trolls.”

Eimers reported the damage to local law enforcement immediately. On July 31, the Maryville Police Department and Blount County Sheriff’s Office announced they had arrested Adam Heimerman, a candidate for U.S. Congress in Tennessee, on felony vandalism charges. Prosecutors allege Heimerman shot and damaged four local ALPR cameras between July 14 and July 22. Major Deputy Chief Ryan Rogers of the Maryville Police Department confirmed to WIRED that Heimerman was arrested in connection with the exact same cameras Eimers had publicly flagged. Heimerman did not respond to a request for comment, and his legal representation could not be immediately identified.

To Eimers’ dismay, many commenters on public posts about the arrest have openly expressed support for Heimerman. One comment read simply: “Buy that man a beer.”

Flock spokesperson Paris Lewbel declined to share how many of the company’s cameras have been damaged in recent months, but told WIRED the firm has received relatively few reports of such incidents. “Damaging public safety equipment is illegal and puts communities at risk, which is why we strongly condemn this type of behavior,” Lewbel said. He confirmed the company is moving forward with its nationwide installation audit, but declined to answer specific questions about the audit’s methodology, timeline or scope. Flock currently operates more than 120,000 ALPRs across 49 U.S. states.

Eimers’ greatest fear, he says, is that the rising tide of vigilante action will get someone killed. He pointed to a hypothetical scenario where a person vandalizing an ALPR is chased by police, leading to an armed confrontation. He says he plans to refocus his advocacy exclusively on roadside and crash safety, and leave privacy-related debates about ALPRs to national civil rights organizations.

Eimers noted that the Flock audit is proof that progress comes from staying focused on his area of expertise. While he will not post new ALPR content, he plans to leave all of his existing ALPR posts public. “If these [cameras] continue to be out on the roadside, America will be safer because of what I posted,” he said.

“I poke the bear too often,” Eimers added. “And this time the bear poked back.”
