The biggest problem is going to be if it got embedded in a tire. The hope is that it’s “just on the side of the road”. But there’s a very real possibility that this could get picked up by someone’s car, wedged into the tire tread, and sit in their garage slowly exposing them and/or their family if the garage is used for anything else. Or any other car related exposure scenarios such as part time rideshare driver or work vehicles. And it could spend some time Slowly getting its surface chipped and abraded by regular driving wear, spreading out the risk… which could be good or bad depending on how large the pieces are.
