New beta version. Slight change to the drafting graphic, you now enter the drafting box when the effect kicks in. The graphic shows when you are within 25m of somebody but the effect unfortunately still only kicks in when you are 5m from somebody making it hard to moderate your speed as you approach them and not over shoot. That said I was trying to draft a spurrer ghost and they aren't the friendliest of riding companions, the lapdogs on my second ridre where much easier to stay with, nice friendly dogs! Also it seems it doesn't work for actual ghosts rather than bkool ghosts but presumably does for real riders.
@Boredman the change of gradient is as good as they can get it, pretty much instantaneous so hopefully it will solve your problems.
