Police pursuits are being viewed as a double edged sword.

Police Commissioner Andrew Coster says a new fleeing driver policy gives officers more scope to pursue offenders.

The Fleeing Driver Framework factors in the threat from the driver, their suspected offence - and the chance they'll offend more.

Road safety and crash investigation expert Hamish Piercy told Roman Travers Police are between a rock and a hard place - and there's always going to be risk.

He says if a person decides they want to take off and aren't pursued, there's just as much risk of them continuing to behave recklessly and going on to crash.
