Pretty much this but another point of difference with say the US is that (Utes) (trucks) in Australia would be classified as "cars" and not commercial vehicles. Which is why you can see so many giant fuck off trucks in the US, they're not part of the legislation ... loopholes. Currently they want Government to have the same loophole as the US, so Toyota -> Hilux Ford -> Ranger etc can keep bringing in their big sellers with no penalty,
I think thays a good compromise. if you then have an issie with a particular user you can block them individually.
