Potential Saving: $4526.40 per annum – or more

Toll roads in Australia are a complete rip-off. In particular during peak periods, Sydney’s toll roads deliver no tangible benefit to the motorist, yet toll roads cost a bomb. Traffic just grinds to a halt on the major toll roads (and the major free roads) - only the drivers stuck on the toll roads can't get off or try an alternative route. Everyone stuck on a toll road in peak-hour is trapped in a linear car park - and paying through the neck for the 'privilege'. The only group benefiting from toll roads are the companies that own them.

Incredibly, the toll road trip below – common enough for people who live in the north-west sector – costs more than $4500 annually.

We tested what happens when you slash that cost to zero using established free roads.

Potential Saving: $800 Annually - Just by Driving Differently

Cutting your car's fuel consumption costs nothing. Cutting fuel consumption could save you – effectively – about 30 cents per litre on petrol, at the time of writing. If you reduce your fuel consumption to a reasonable extent, you could save up to $800 annually. All you need to do to reduce fuel consumption is modify your driving behaviour.

Here's the detail on cutting your fuel bill by changing how you drive:

As if the cost of living needed to be under any more pressure: The price of petrol is out of control – again.

Basic unleaded petrol looks like smashing through $1.50 a litre before the weekend – and you’ve got to wonder where all that money goes. Not to you and me, that’s for sure.

If you took a litre of petrol – let’s call it $1.50 – what’s the breakdown? Who pockets the lion’s share? Who’s getting rich? Because someone is.

Here’s how it works out.

French cities seem on the verge of banning SUVs to improve pollution. But is banning 4WDs really such a hot strategy to reduce CO2 in the world’s big cities? Where do passenger vehicles really fit in when it comes to greenhouse?

The big French cities say they’re in the process of banning gas-guzzling vehicles – including 4WDs – in an attempt to curb emissions.

The exact scheme to be put in place – exactly which vehicles, in exactly which neighbourhoods, and exactly what penalties could be enacted – are at this stage still unstated. But the intent to proceed with the project has been
