The Washington Post reports on a moped accident death in Maryland. From the report, it sounds like a classic "left turn, did not see the moped/bike/motorcycle accident.
In these cases, the Defendant is responsible for the death of the moped driver, assuming the facts are as I think they are. But juries hate bikes, motorcycles and, particularly, mopeds. Why? Because jurors can imagine missing motorized bikes and bicycles and because everyone has seen these vehicles used inappropriate on the roadways. Almost invariably, regardless of the facts, these cases are a fight.
