That legislation have been in place for over a year now...
I do not understand why you'd want to do this idea? You'd only draw attention to yourself as a smart arse.
Also... merely videoing everyday people who appear to be speeding would not really constitute as hooning. If that were true then every time an officer pulls someone over when doing road side speed checks, they would have to impound their vehicle.
Extract from Explanatory Memorandum:A member of the police service will be empowered to impound a vehicle for 48 hours where he or she reasonably suspects that the vehicle has been used in the commission of an offence against section 62A (wilfully driving a motor vehicle in a manner that causes a loud noise or smoke to be emitted from the vehicles tyres) or an offence of dangerous driving causing death, dangerous driving causing bodily harm, reckless driving or dangerous driving committed in circumstances of aggravation (i.e. the driver was racing another vehicle, attempting to set or break a speed record, testing the capability of the driver or vehicle, deliberately causing the vehicle to emit noise, smoke or lose wheel traction with the driving surface).
Extract from ROAD TRAFFIC ACT 1974 (WA):
s 62A. Causing excessive noise, smoke
A person who wilfully drives a motor vehicle on a road or in a carpark so as to cause —
(2) excessive noise to be made with one or more of the vehicle’s tyres; or
(2) smoke to come from one or more of the vehicle’s tyres or a substance on the driving surface,
commits an offence.
Extract from the Second Reading Speech for the Bill that introduced the road rage provisions into the Road Traffic Act 1974 (WA):
"The bill removes the current requirement for police, when considering whether to impound the vehicle of a hoon driver for 48 hours, to have personal knowledge that there are grounds to impound the vehicle prior to doing so. For example, in a situation in which a police officer arrives at a scene after the impounding offence has occurred, the police officer will be able to impound a vehicle on the basis of observations from other witnesses, admissions made by the hoon and other forms of evidence. … This does not mean, however, that a police officer will be able to impound a vehicle on the basis of a malicious allegation made by another person. A police officer’s reasonable suspicion must be based on evidence that will stand up to scrutiny in a court. A vehicle will be impounded only on the basis of a civilian witness report if it is corroborated by other forms of evidence gathered by the investigating police officer."
