A man with a lengthy criminal record for terrorizing the streets has been sentenced after assaulting a woman and her teenage daughter in an extreme road rage incident. Nathaniel Radimak, 39, was sentenced in a Hawaii court on Wednesday for a 2025 viral attack where he aggressively confronted Diane Ung while she was teaching her daughter, Iwalani, how to park. At the time of the attack, Radimak was on parole for a similar crime in California. He was originally sentenced to five years in prison for that incident but was released after less than one year, only to unleash violence once again in Hawaii.
Details of the Attack
The shocking road rage incident unfolded on May 7, 2025, when Radimak sped past Ung, who was teaching her daughter how to parallel park outside their home. He nearly clipped their car, prompting her daughter to yell at him to slow down. The comment caused Radimak to turn his car around and confront the mother and daughter. Ung later told local news outlet KITV that her baby was asleep in the backseat when Radimak confronted them. She recalled that he yelled at the teen before approaching the window and punching Iwalani in the face.
The furious mother then leaped out of the vehicle to defend her daughter and hurled an iced coffee at his car. He came running across the street and struck me like a Superman punch right inside my face, she recalled. I fell down to the ground, big gash in my head. And I'm just like, 'Go check on the baby. Don't worry about me. Go check on the baby,' Ung remembered telling her daughter. Ung had a cut above her left eyebrow from the attack and required eight stitches.
Legal Proceedings and Sentencing
Radimak was charged with two counts of third-degree misdemeanor assault and one count of felony unauthorized entrance into a motor vehicle in the first degree. He initially pleaded not guilty but entered a no contest plea earlier this week. Deputy Prosecuting Attorney Hon-Lum Y. Cheung-Cheng said of the sentencing: Based on the defendant's presentence investigation, it is evident that the type of criminal conduct in this case was in no way a one-time aberration for the defendant. Time and time again, the defendant keeps engaging in similar conduct. The roads may change, but the defendant's behavior does not, and will not change.
Radimak's attorney, Rosa Flores, argued that his actions were a result of schizophrenia, bipolar disorder, and post-traumatic stress disorder. He was actively seeing his medical providers in the months leading up to the May 2025 incident, and the medication kept getting changed, she told reporters. He was reporting side effects to that, so he was actively trying to see what he could do about seeking better medication.
Radimak apologized for his crimes at the hearing, telling the court: This was not on the agenda that day. I regret it, like I said. I take accountability. Just feel bad about it. It shouldn't have happened. I really need a certain kind of treatment. Judge Clarissa Malinao determined that Radimak was a danger to the safety of the public with a lengthy history of similar road rage crimes.
Previous Criminal History
The sentence comes after Radimak made headlines in California for being the Tesla road rage guy. He had terrorized multiple women on the road and was caught on camera using a metal pipe to bash the cars of his victims in numerous unprovoked attacks between 2022 and 2023. Radimak was found guilty of criminal threats, vandalism, assault, and elder abuse in the California case. Attorney Gloria Allred, who represented four of his victims, previously told the Honolulu Star-Advertiser that she would seek his extradition from Hawaii. However, Radimak's attorney said his parole will expire in August, so he will serve his sentence in Hawaii.
Radimak has now been sentenced to seven years in prison, with credit for a year already served since his arrest last May. The Daily Mail has reached out to Radimak's representation and the county prosecutor's office for additional comment.
