The number of electric vehicles in Britain has grown significantly over the past decade, with the country registering its millionth electric car in January. However, the pace of growth is slowing, causing concerns among policymakers and car manufacturers. While electric car sales are still rising, the demand is currently being driven by fleet buyers rather than individuals. This shift is leading car makers to reconsider how quickly motorists will switch from petrol and diesel cars to electric ones. The Office for Budget Responsibility has revised its forecast, lowering the estimate of EV sales from an earlier prediction of 67% to just 38% of new car sales by 2027. This trend is not unique to Britain, as growth in Western markets is also slowing, as seen in the United States where the increase in electric car sales dropped from 15% to 1.3% in the final quarter of 2023.
