aer you actually stupid you can't even see anything other than a blurry back wheel. there is no way you could distinguish that back wheel from any other.
you don't need to be sorry because i don't care at all that i didn't recognize him. and you claim you can recognize him by his back wheel which looks no different than anyone elses, and by his black helmet, which 50% of riders have, so no, everything you are saying is perfectly fine.
