Perhaps the wording of "Vehicle on hard shoulder" could be changed to "Broken down vehicle obstruction" or something else similar. This way it is only added when a vehicle is in a live lane. I find a lot of people add this report when the vehicle is not in the way, sometimes just in a layby even. There is no need for the report and just causes unnecessary traffic delays. It would be the same as saying "Lamppost ahead" if it's not in the road or obstructing traffic, then I feel the report is more of a distraction than the actual vehicle that has pulled over.
