I once saw a deer run right into the side of a car in front of me, cave in the door like that, slide a bit on the road, recover and run away.
I had a deer hit me while on a mc(I was the one riding the mc...

) I came around a turn and started slowing for fear of deer, and sure enough they were crossing(3 to 5 of them), so I got it down to 5mph and should have stopped, but headed for the last ones butt and would have missed it, but the deer did a 180º(squirrels), and knocked me off the road.
Always wait for them to move away before going though and look for stragglers. What scares me now are pll that follow too close, twice I've gotten my mc & new coupe down to a stop(I touched a deer with my car, but no damage) ....... but things can change real quick with a 4000 lb. car stuck up our rear.......... in most cases ppl don't pass they just ride our rear and get no where faster.
