His lawyer Peter Attwood told Judge Peter Rollo that despite the police summary of facts, Gilmor insisted there had been a verbal exchange between him and the victim prior to the attack.
Mr Attwood said his client, who had earlier pleaded guilty to charges of driving in a dangerous manner and wilful damage, was remorseful and ashamed of his behaviour which happened during a stressful time his life as he was dealing with a relationship break up, and "sought refuge" in methamphetamine to try to cope.
Gilmor had taken rehabilitative steps to address the causes of his offending and he now had a fulltime job and accepted he should pay full reparation, he said.
Judge Rollo told Gilmor his actions were "completely unacceptable" and he could easily have been facing a prison sentence but gave him credit for addressing the issues in his life.
He was sentenced to 300 hours community work and 12 months intensive supervision, which included a penalty for other unrelated violence matters. Gilmor was also ordered to attend a Living Without Violence course, pay $2100 reparation to his victim and disqualified from driving for nine months.
In the second incident, David Henry Corstorphine, 52, was sentenced on a charge of reckless driving which began with him almost tailgating his victim on Fraser St on September 4.
During a verbal exchange between the two men, the victim threw a water bottle at Corstorphine's car, before Corstorphine drove into the other car and wrote it off.
Judge Rollo ordered Corstorphine to pay $1000 emotional harm reparation to his victim,
and disqualified him from driving for 6 months.
The third road rage incident involved Scott Sinclair Campbell, 34, who admitted a charge of careless use of a motor vehicle and failing to stop to ascertain injury.
On October 4, Campbell became frustrated after a group of six cyclists in front of him did not allow him to overtake as he was driving along Welcome Bay Rd.
When he got past the group he slammed on his brakes to "scare" off the cyclists but the victim, who had been cycling a few metres behind, ended up smashing into the back of Campbell's car.
Campbell drove off but returned 15 minutes later to check on the victim, who was treated at Tauranga Hospital for abrasions and cuts to his face, hands and legs, the court was told.
Judge Rollo disqualified Campbell from driving for six months and ordered him to pay $5000 reparation to his victim at $50 a week to replace the bike which was written-off.
Outside court head of Western Bay of Plenty road policing Senior Sergeant Ian Campion said there had been a noticeable increase in road rage type incidents in recent weeks across the district.
These types of incidents were both unhelpful and totally unacceptable, and would not be tolerated, he said.
Mr Campion said motorists needed to accept the roads were far busier now and they may be momentarily inconvenienced when trying to get from A to B.
He said people needed to be patient and show tolerance to others on the road.
