With deer, moose or other big critters on or near roads its best to brake hard, even after they get out of the way. Don’t steer to avoid until collision is eminent, steer behind them whenever possible. Don’t drive past them at over 20 mph. Many of them behave as if they want to get hit and wait to jump into your path at the last second.
The speed up idea sounds pretty stupid. Not only is the potential energy greater, but deer often bound and vary in size; their CG AGL is not consistent. More cars, and even trucks, today have sloping hoods. There are too many variables to bet that a deer will fly over the cabin if hit at over 70 mph.
