one time i hit a deer with my truck. it wasn't really hard. i was sitting there looking myself and my passenger over. the deer got up and flipped out and charged my door. i still think it was confused and was trying to get away not deliberately charging me. still doorless would have been painful. there are a lot of other dangers from going doorless i don't think deer is very high on my list.
