A would-be street racer had his licence suspended and his registration plates seized after his Subaru WRX was recorded going 194 km/h in a 90 km/h zone on Saturday morning.

The 24-year-old man from Merrylands was arrested and charged with street racing, dangerous driving and speeding as he raced with another car on the M4 in Auburn. The car turned off at James Ruse Drive and was pursued by police, before pulling over.

Inquiries are continuing into the case of the second driver, who is known to police.

So far in New South Wales this year, there have been 331 fatalities on the roads, slightly up from last year.

Assistant Commissioner Michael Corboy of Traffic and Highway Patrol Command said that the reckless behaviour displayed this morning could easily have contributed to that tally.
