So its totally cool to ask a stranger that youre keeping pace with if you can draft with them? after exchanging hellos and its clear that I can keep their pace is it totally fine to just be like "Hey man im tired and late to work, mind if I draft you I won't hug your wheel?" Ive never asked or drafted on anyone but my father lol. I wouldn't get on their wheel to the point where I "need" them to signal, can't trust a rando to do that and don't expect them to.
