Steve Gooding, from the RAC Foundation, said: "We should all choose the right vehicle for the right trip to cut the size of our carbon footprint.
"It is right to question if suburban drivers need a car capable of ploughing over rivers, across fields and up steep hills just to pop to the shops."

Actually, don't bother. I'm in the AA. Thankfully.
Edmund King, from the AA, told the BBC: "Talk of banning the advertising of SUVs is a naïve approach. Some of the cleanest cars come in the SUV shape but are all electric such as the Jaguar I-Pace, Tesla Model X or Hyundai Kona.
"The auto industry is developing a wide range of cleaner, greener vehicles with some of the best in SUV styles," he said. "Not all SUVs are large. Small SUVs are among the most popular cars on sale, because they usually offer the high-set driving position, practicality, safety and looks of more traditional off-roaders, but without the high price, running costs or emissions."
He added: "Cars like the Nissan Juke are often the family car of choice in suburban areas."
It seems the long march through the institutions hasn't quite made it to the AA yet.
