Nathaniel Radimak, a serial driver of a California Tesla car with an aggressive driving style, was released from prison after less than a year of his five-year sentence

A Tesla driver armed with a pipe who spread fear and terror with his tantrums on California's highways was released from prison on Wednesday less than a year after beginning his sentence, with his victims saying they were “disappointed” with the state's justice system.

Nathaniel Radimak, 37, was released from state prison on parole Wednesday after serving just 10 months of the five-year sentence handed down last September to the hotheaded electric car driver, according to KTLA 5.

The California Department of Corrections and Rehabilitation said Radimak had “fully served his statutory sentence” and was granted 424 days for time spent in pretrial detention, 212 days for actual detention and an additional 212 days for good behavior.

During Radimak's terror campaign, he smashed passing cars with a metal pipe, made threats, and harassed motorists throughout Southern California.

In a now-viral video, Radimak jumped out of his 2022 charcoal-colored Tesla Model X without license plates on January 11, 2023, armed with a pipe, and rammed the truck behind him. Radimak drove away after hitting the vehicle several times.

Radimak was arrested weeks later, with police discovering steroids and more than $30,000 in his car.

After his arrest, it emerged that Radimak had a long criminal record “spanning nearly two decades and spanning multiple states,” KTLA reported, citing prosecutors.

Last September, Radimak was found guilty on several counts during his 2022-2023 killing spree.

However, the aggressor pleaded guilty to assault, vandalism, elder abuse and criminal threatening and was sentenced to five years in prison after negotiating a deal with the prosecution.

Several women who were victims of his killing spree are now free and back on the streets of California. They are outraged by his release and are “worried” about their safety.

Well-known attorney Gloria Allred represents three victims of the Radimak attack.

“I am very disappointed with the overall outcome of this case leading up to his release,” one of Radimak's victims, identified as Jane Doe, told KTLA on Wednesday.

“I strongly doubt that Radimak has learned from his mistakes and will emerge a changed person in a short period of time.”

“I'm worried he's going to try to find the victims whose names have been released,” Jane Doe said.

Allred said her clients were informed the day he was released from prison that he would be released.

“His early release has shocked and disappointed many of the victims I represent,” Allred told NBC Los Angeles.

“Many of these victims were never questioned about the agreement and never had the opportunity to speak at the verdict.”

Another anonymous victim of the Tesla terror attack, identified as “Jane Doe 1,” told NBC she “prays” that his “brief time behind bars has taught him a lesson.”

Like Radimak's other victims, she feels abandoned by the California justice system.

“Parole boards continue to release offenders after serving the minimum sentence, thereby endangering many innocent people and sending the wrong message to criminals,” she said, criticising the state's leniency in dealing with criminals.

According to data from the Public Policy Institute of California, California's violent crime rate was 18% higher in 2023 than it was when Governor Gavin Newsom took office in 2019.

In 2022, the number of aggravated assaults in California increased by 25.3% and the number of homicides increased by 33.9% compared to 2019.

Almost all inmates in California automatically receive a Good Conduct Credit (GCC) upon admission to the prison system under Proposition 57, which was passed in November 2016 before Newsome took office.

According to a 2023 CBS News report, GCC “reduces prison sentences for violent defendants by 33.3% and sentences for nonviolent defendants by 50-66.6% on the day of arrival at prison.”

Since 2019, tens of thousands of felons have been released early on suspended sentences and then rearrested for violent crimes, the outlet reported.

“We don’t know if (the CDCR’s programs) are working,” Heather Harris, a senior researcher at the Public Policy Institute of California, told the outlet in June 2023.

California lawmakers passed a law requiring the CDCR to track the effectiveness of its rehabilitation programs following a state audit in 2018.

However, in 2019, Governor Newsom vetoed the bill, saying it would “require the California Department of Corrections and Rehabilitation to hire a researcher to conduct a recidivism analysis on the effectiveness of rehabilitation programs and submit a report to the Legislature. The goal of this bill can be accomplished administratively,” CBS reported.
