Maybe cars and car travel will become unaffordable again now that there's no longer a local product.
I certainly hope that the lack of a local industry needing to be protected and subsidised will prompt governments to start weening private car users off the lavish subsidies they currently enjoy.
The big problem is the rate of car usage for short journeys, especially the school run. These journeys carry the greatest environmental cost as the cars are not being run long enough to get the engine properly warmed up, and they also make up the greatest portion of the congestion problem.
We need to be shifting to direct road pricing, so that those roads owned by the state governments (at least in metropolitan and commuter belt areas) can be effectively self-supporting instead of a drain on the public purse.
My grandfather said that ordinary people didn't have cars at all in the thirties but suddenly after the war Holden bought out a mass market car that everyone could afford.
It wasn't just Holden, it was a result of post-war prosperity. The distinctive aspect with General Motors was their marketing strategy of using an Australian brand name to achieve greater sales than other manufacturers' superior products in the same price bracket. Just think what would have happened if other manufacturers did the same - if, for example, the Morris Minor had been sold under a unique Australian brand name the whole large car market would probably not exist in Australia these days and there wouldn't be the aversion to front wheel drive cars.
South Australia is certainly worse off for it, when you consider the dismantling of the Adelaide tram networks.
In my opinion there's a high chance 'average' people won't be able to afford cars again …
For sure, the desperate attempts from governments of both major parties to hold off Peak Car in Australia have been a complete failure.
However, people will cope and adapt - just like they used to!
