Peter Abbott got out of his car and approached a scared Samantha Isaacs after the minor incident outside a Tesco petrol station.
Ms Isaacs locked her doors and began filming the irate 60-year-old as he pounded his fists on the windscreen and unleashed a foul-mouthed tirade.
Mr Abbott called Ms Isaccs, who runs a TV production company and has worked with Prince William and Alan Titchmarsh, af****** tarts, a ‘sl**’ and a ‘wh***’.
He was spared prison when convicted at Poole Magistrates’ Court on May 24 of using threatening words or behavior to cause alarm, distress or fear of violence.
District Judge Orla Austin ordered Abbott to attend an anger management program called Creating Positive Connections and pay Ms Isaacs £300 in compensation.
She said: ‘I believe this was an extremely serious matter. Ms Isaacs was a lone woman in her car, it was an ongoing incident, your level of anger and aggression was extremely high and your language was extremely offensive.
“You put her in great fear and it has had an ongoing effect on her life and on the bystanders who intervened.”
The road rage incident happened on August 25 last year when Ms Isaacs, in her late 50s, left the Tesco Extra petrol station in Bournemouth, Dorset, just before lunchtime.
Abbott, who was shopping in the main store, drove in front of her, causing her to slam on the brakes.
The mother-of-three honked, prompting Abbott to make rude gestures at her before stopping his Toyota car and getting out.
Video footage filmed by Ms Isaacs showed him shouting at her: “Can you fucking see me, you bloody idiot?” He then called her a “slug” and a “whore” and put his head against the windshield.
A male motorist intervened and called Abbott a bully. The Good Samaritan told him “what’s wrong with you, she’s a woman on her own”, to which Abbott replied “she’s a bloody nasty woman”.
During the trial, Ms Isaacs told the court: ‘I had just left and a car came out of the shopping area and completely cut me open to the point where I had to slam on the brakes so hard that all my stuff fell off the passenger seat . on the floor.
“I honked as if to say ‘look out’. He turned around in the car and started gesticulating, then he got out of the car and started shouting at me.
“He was banging on the windshield and my door with both fists. I was scared, so I started filming it.”
Robert Salame, prosecuting, read out a victim impact statement from Ms Isaacs which said: “I now don’t trust any motorist, my confidence in driving has taken a huge hit. Having driven 30,000 kilometers a year for work, I am now going get started on road work that is further away.
“I’m so angry that he took away my job satisfaction. I’m scared all the time when I drive now.”
Abbott, a self-employed translator, was described in court as a “studious” man but accepted he also had a temper problem that needed to be addressed.
Representing himself, he said: “I have been isolated for quite some time due to the nature of my work. I’m a translator and I only write documents, so I spend a lot of hours, days and weeks locked in my work. apartment behind the computer.
“Since coming back to the UK I have noticed that my relationships with people are a problem. At the time of the incident I had no contact with friends or family.
“I knew before that I had a problem with my mood. If I had been smart, I would have sought help sooner, but I always put my work above all else.”
He said he regretted his part in the incident but claimed media coverage of the case had “destroyed” his professional career.
A reference from an old friend who is a professor described Abbott as a “peaceful, introverted and inquisitive man”.
Abbott, from Bournemouth, had denied using threatening words or behavior to cause alarm, distress or fear of violence, but was found guilty after a trial.
He was given a prison sentence of twelve weeks, suspended for eighteen months.
Abbott was also banned from driving for 18 months and ordered to pay £300 court costs.
