Harry-Wragg's 'just a thought' happened to my father in law. Many years ago he was involved in a 'cutting up' incident on the way home from work, him being the cut up.
Tempers flared and my husband, in fiery years of youth, kicked the other drivers door, denting it. The lights changed and both drove off.
A couple of days later 2 plain clothes cops came to father in laws house to question him. He said his passenger was a stranger he gave a lift to and he couldn't help.
Nothing more was heard.
