Wollongong Local Court heard Michael Zadel was upset about a failed relationship when he was spotted by police speeding and driving dangerously about 12.10pm on November 11, last year.

The 27-year-old was driving westbound on Five Islands Road at Port Kembla when police noticed his silver Holden Commodore weaving in traffic, failing to indicate and accelerating harshly.

At the time, they clocked him doing speeds up to 110km/h.

It was as they tried to catch up with him that he turned into Springhill Road and accelerated again, reaching speeds of more than 130km/h in the 80km/h zone.

When pulled over by police, he was asked if he knew why they had stopped him and he replied: "Yes, for driving like an idiot."

The police fact sheet noted it had been raining heavily at the time.

Yesterday, the court heard Zadel had been upset about a relationship breakdown at the time of the offence and has been seeing a psychologist ever since.

Sentencing Zadel, the magistrate, Susan McGowan, told the Warrawong man, who has a prior similar conviction, he would be jailed if he continued to offend.

"Your manner of driving did present an unacceptable danger to the community," she said.

"Unless there is any improvement, you won't be out and about much longer."

Zadel was given a suspended jail sentence to be on good behaviour for 12 months.

He was disqualified from driving for two years.
