My recommendation is to use helmet mounted action camera. It records what your head is pointing and makes it easy to switch on and off. Allows you to capture confrontation if someone tries to argue with you. Plenty of good choices... But remember the legal stipulations - for example: If you ride like a.s.h.le and camera captures it, its evidence against you. If you are proven to delete it - felony - offence punished more than your traffic violations.
