@expectbetterUK@SpannersReady Distance covered will be slightly different with each different line they take. Basically they would need a way to constantly monitor the outside diameter of the tire while it's running around the track.
@SpannersReady The rule says max speed but what is measured is average speed from one point to another which is assumed to be the path the cars will take. Either the rule should be updated to reflect how it's actually implemented or the implementation should change to reflect the rule.
