Hazard lights should only be shown on a stationary vehicle ( is what I always thought the law said ) so if they see your hazards in their mirror they should think that you are NOT moving. And if everyone thinks its a good idea to have them on when moving then genuine non moving hazards are likely to get ploughed into as people would be thinking they are moving.
I don't do rain or threat there of. dry rider only with no shame.
