Oil is used for a lot more than just cars: petrochemicals are a massive industry. Everything plastic is a petroleum product. Fertilizer is a natural gas product. About 1/3 of fossil fuel electricity generation is oil (other 2/3s are coal and natural gas). There is no way to stop producing oil while maintaining living standards in the near to moderate future. The turbine blades on wind farms are composites made from petroleum products. PV arrays are encapsulated in petroleum products. Tires are made from petroleum products. You can make these from renewable sources but it is much more expensive and the supply chains to do so don't exist yet at scale.
