This year the BBC is looking into the future, in key areas of science, politics, education and our personal life in a series called What If? As part of this, 6 Minute English looks at the question: 'What if everyone had a car?'
There are already a billion cars in the world but what would be the consequences if there were even more vehicles on the road? Rob and Jennifer discuss what might happen and they talk about some designs for cars of the future.
We'll be hearing some driving-related words and phrases along the way.
