Why do you speed up to hit a deer and not slow down?

It is shameful to speed up intentionally when one can slow down watchful of the traffic following.However if there is no option, then after hitting a deer crossing the road it is best to continue driving to avoid any fatal accidents from the traffic following.The injured deer may totter off the road or lie on the road causing accident to the oncoming drivers who may try to avoid hitting it at risk or just run over it. It is best to report about the injured deer to the highway patrol.

Subsequently the animal will be crushed or be a hazard obstacle till the highway patrol removes it.

Another View: ACTUALLY - the best advice is NOT that you speed up, but that you take your foot off the gas, but maintain your straight-ahead direction of travel and NOT try to swerve to avoid the animal.

Obviously you should not intentionally aim to strike them but, despite the above response, more accidents and injuries to HUMANS are caused by trying to swerve to avoid animals than by steadily maintaining your direction of travel.
