Drafting ONLY works when you are sitting right up pretty much touching the car in front
And it seems that only perfect draft scores are shown

This is only one video i captured - i did a previous race that was at the alps course and i was literally sat on the bumper of the car in front for about 5 seconds … i have had ZERO drafts (effect or score) in a hundred races now … not possible!

Try giving the car a nudge
Mine didnt register until i gave them a nudge first
