Holden Commodore
Commodore have been given a bad name due to the fact the drivers of them are the worst you could ever see on the road.Also to the fact that they are built out of rice paper. They do the following:
1- Weave in and out of traffic even during peak hour.
2- Will try to race you despite any Commodore they own. Ie If they own a VT and you own an Aurion they will still try and race you even though they have no chance. 
3-If you are on the highway, and doing 10km/h above the speed limit, they will still be going faster than you
4-Tailgate anywhere anytime
5-Sit on the right lane of the highway and never ever move as they tend to think they own the road
6- Commodore owners thinking they have Ferraris 
7- Foglights on during the day to give you the impression that they look cool and that you should get out of their way.
8- Putting later model commodore bodykits on earlier model commodores to make them appear cool. Body kits often do not appear to fit properly
9-Typical australian male with your base model Commodore and hubcaps and by adding a spoiler they are all of a sudden thinking they have a BMW or Merc and they are king
All of these things add up to Commodore drivers being the worst on Australias roads. 

"Wow im doing 130km/h and that Holden Commodore is passing me like im standing still"

"Hey mate, see that car coming with the fog lights on? I bet you $100 that the car is a Commodore"

"Bloody Commodore tailgaiting me!"

"Oh look at the accident on the news, another Commodore driver lost control of his car"
