Imagine teaching your daughter how to parallel park — a normal, quiet afternoon — when suddenly, a Tesla comes flying past, nearly clipping your car. Your teenage daughter yells out, “Slow down!” That one moment changed everything for a Honolulu mother and her family.
The driver didn’t keep going. He made a U-turn.
Nathaniel Radimak, 39, got out of his Tesla and walked straight up to their vehicle. “What the f— did you say to me?” he demanded. “Say it back to me.” Before the family could react, surveillance footage captured him lunging at the car and punching the teenage girl directly in the face.
When the mother, Diane Ung, stepped out to protect her daughter, things got even worse. She threw her McDonald’s iced coffee at his car in desperation — and Radimak responded by charging across the street and delivering what she described as a “Superman punch” directly to her face. She fell to the ground with a deep gash in her head.
Her baby grandchild was in the car the entire time.
What makes this case even more alarming is that this wasn’t Radimak’s first time. Back in California, he had already built a reputation as a violent road rage attacker — going back to 2020, sometimes even using a metal pipe. In 2023, he was sentenced to five years in prison. He served less than one year before being paroled — and then moved to Hawaii, where he continued his pattern of violence.
This week, a Honolulu judge sentenced him to seven years in prison after he pleaded no contest to assault and unauthorized entry into a motor vehicle.
In court, Radimak said he “regrets” his actions. “This was not on the agenda that day,” he told the judge. “I take accountability.”
For Diane Ung and her daughter, those words may offer little comfort — but justice, at least, has finally been served.
