It’s not really that simple. Here’s a breakdown of central government road funding. https://www.gov.uk/government/publications/roads-funding-information-pack/roads-funding-information-pack https://www.gov.uk/government/publications/roads-funding-inf... So central government commits very heavy funding to road building and maintenance such as through the Major Road Fund, but also many maintenance schemes at different levels. Some local governments choose to forego some of this funding in return for receiving retained business rates instead. However retained business rates is collected by central government and considered central funding. Ultimately money is a fungible commodity. It is true there’s no direct relationship between road taxes and road maintenance, but whatever petrol taxes pay for would still need to be paid for somehow if they went away.
