I get that occassionally, usually from kids who do the fake jump out in front of me. I've started to be less annoyed by it as I've just consoled myself with the fact that myself and my bike are over 100kg and if I hit them at 15mph, they'll fuck themselves up.
Police called today and asked me to drop in the footage asap, at least it's being taken somewhat seriously.
