Moto Glove Incident

Object in the road, its noticed its probably a group riders glove. Original spotter is too deep to it to stop. I say over comms that I'll get it. Its difficult for me to stop. The following rider didn't hear the conversation clear, looked at the ground where they saw me wiggle because I slid my rear break. They are looking for the slick obstacle that isn't there. When they look back up I'm completely stopped. This could have been extremely worse.
