Car Myth Buster - Driving With Your Windows Open Saves More Petrol Than Using The Aircon

Each week, Noni takes on a popular car myth and “busts it” live on-air -  from “The more weight in your car, the slower it goes…” to “Manual cars are more fuel efficient than automatic cars…”

But it doesn’t stop there:

 The myth is also shared online ahead of the show, where listeners and followers are invited to vote on whether they think it’s true or false. The results are revealed live on-air, followed by insights and the final verdict.

This week's statement is:
"Driving with your windows down saves more petrol than using the aircon." – Is it true or is it false?
