Thanks. I was running full speed so I may not have been able to hear, but nobody said anything about that. I walked around to find the ball later and the entire street was lined with cars on both sides, so I either hit the middle of the street, got super lucky to miss them all, or cleared them (unlikely but I didn't see).

At some fields, cars do get hit and it feels bad. I haven't hit one in ages though so my record is clean/expunged.
