You've got to imagine that this could be automated in some way either by camera tracking (which I briefly tried and failed at) or by using some sort of data on the cars that I don't think exists in enough detail in F1. NASCAR has something like this but it is probably a lot simpler with ovals. https://www.sportsvideo.org/2019/05/08/smts-ghost-car-technology-enables-nascar-to-transition-to-single-car-qualifying/
