Call me knaive, but the way I see it is the RTA and engineers are only responsible for the vehicle up until it is presented and approved for registration, right up until the point where the number plates are bolted on since you cant leave the rego office without them affixed.
Once ANY vehicle leaves the carpark it is then in the hands of the police, mobile RTA enforcement officers (or equivalent in other states) to ensure or penalise ongoing compliance to rules or lack thereof.
If any states RTA was to approve a car with seatbelts bolted through glass they definitely need a good jab with a pineapple.

In reality any clown can register a KE20 corolla and then fit 4 straight side pipes, 12 inch wide mags and a plethora of other trash but how in gods name can anyone but that idiot be held responsible for those actions??

No amount of restrictions, rule changes or prohibitive laws will stop an idiot from flouting all the rules including the law of common sense.
