.AMERICANS like to super-size-- and certainly not simply their convenience food. They favour significant sport-utility motor vehicles (SUVs) and also pickup trucks over little cars and trucks. Some 8.7 m hit the road in 2023, making up more than half of all sales of brand new motor vehicles, according to JATO Dynamics, an investigation company. Although International cars and trucks are also getting bigger, American ones still have a relaxed top: in 2022 the common cars and truck sold in America examined 1,857 kg, nearly 20% more than the average in Europe. Wide roadways and also large parking spaces support this desire for large adventures-- and so carries out the regulation. Yet a loophole that for nearly half a century has incentivised purchases of big cars will soon be secured. Will that lead Americans to buy smaller sized autos?
