did you read them properly?
you have to be caught drink driving 4 times before they take your car for good, conversely if your car is found to be too loud, or you accelerated too quickly according to the officers discretion (even if you didnt exceed the speed limit) 2 times thats it, cars gone.
they are saying that people that drink and drive are less dangerous than a car with an exhaust thats too loud.
the bikie laws, thats guilt just by knowing someone, you do not have to have done anything wrong. they then massively ramped up the penalties for anything considered a group, you can get hit with and additional 15 years in prison for any injury to someone that causes as little as a scrape thats broken skin.
