If you want urban sprawl like we have in Canada and I assume Australia, then go for it. Denmark doesn't let their cities look like crap. I say this as someone that loves my home city, Toronto, but cars are a collective action problem. To any one person it makes sense to take the car instead of the bus, but if we all take the car then we all get there 2 hours later than if even half of us took the bus or streetcar.
