Strikeforce Puma, a joint effort by Highway Patrol, Traffic and general duties units, has been established to target drivers with a history of licence offences, repeat drink-and-drug drivers and social-media hoons.

Friday's announcement was triggered by the high-profile case last Boxing Day in which the entire Falkholt family - including Home and Away actress Jessica - was killed when a serial driving offender smashed into their car on the NSW south coast.

Highway Patrol Commander Michael Corboy said 21 people in 2017 and six innocent people, so far this year, have lost their lives to unlicensed, disqualified or suspended drivers.

"Those are 27 deaths we want to negate," he told AAP at the launch of the strike force in Sydney on Friday.

Mr Corboy said bad drivers, particularly those caught on dashcam footage by members of the public, could expect a knock on their door from strike force investigators.

Emergency Services Minister Troy Grant said Strikefore Puma would investigate dangerous driving shared in videos on social media.

"They're not heroes, they're idiots," he said, noting many who share their burnout and wild driving videos online hide their faces for fear of being charged.

This year 170 people have died on NSW roads while 387 people have died in the past 12 months.

The driver of the four-wheel drive that slammed into the Falkholt car had a shocking driving history and was on his way home from a Nowra methadone clinic when the crash occurred.

The community outrage that followed the horror crash was among the catalysts for establishing Puma, Mr Corboy said.

"We were outraged ourselves," he said.

"One of the reasons we established Strikeforce Puma is to make sure the community feels safe driving on the road."

He urged community members to contact police with tips and videos of dangerous and menacing drivers.
