Twice, on this tour, I've been in a situation where a dog has been chasing me, and a speeding vehicle hit the dog. Neither time the car stopped. One time I was with friends, once I was alone. Both times we/I found the owners, and the second time the dog was still alive so I stayed with it until the owner came. Obviously neither of these was an incident of violence against a cyclist, but it would have been decent of the driver to at least stop and make sure everyone is okay, or deal with contacting the owner.
Also, in both these situations, there was absolutely no time to get a license number.
I've had a ton of people swerve close to me, shout, lay on the horn, and give the universal suggestion. Once a bunch of rednecks in a truck in Michigan followed me for a bit threatening me and accusing me of being homeless. So far no flying bottles, at least!
