Not that you have bothered to show us your calculations. https://pod-point.com/guides/electric-car-vs-petrol-car-cost-comparison-in-2024?gad_source=1&gclid=CjwKCAjw_4S3BhAAEiwA_64YhiPZWvyTJXK_rDvTwGF4EV8_06OHAjhgHsfYEukLpko6G2r3IHrERRoCD9sQAvD_BwE&gclsrc=aw.ds does suggest that you have got it wrong. Figuring in the depreciation of the battery is legitimate, but you have to compare it with the depreciation of a internal-combustion-engined car which is also pretty dramatic, and you haven't bothered to do that either. -- Bill Sloman, Sydney
