Do P plater HiPo band work?

[AWD Chaser]

Hi guys,

Do the bans on p players driving hi performance cars actually work? Had it reduced any metrics since its introduction?

The reason I ask is in the example of the quoted article below, is there much point in hi performance bans?

I'm not questioning whether or not the bans are a good thing, I'm just questioning the effectiveness/reasoning of having the bans in the first place.

A Canberra woman's number plates were confiscated after she was caught at 170km/h in her Holden Barina near Goulburn over the weekend.
Police spotted the car, a red Barina, speeding at 60km/h over the signposted limit along the Hume Highway near Goulburn on Saturday afternoon.
They pulled the car over, and a 21-year-old Canberra woman, and immediately suspended her NSW visiting driving authority for six months and stripped the car of its ACT number plates for a period of three months.
