I' ve been in the insurance biz for 26 years and NEVER have I seen any evidence of any concern over deer here in Pa. Insurance companies love anything that causes claims that they can reasonably track and predict! Deer collisions are statistically predictable over large numbers. If an insurance company can expect x dollars per car in deer related claims in the state, they get to charge x+ their expected profit in premiums!

The only kind of claims that bother insurance companies (in the big picture) are the ones that they have a tough time predicting with their bean counter formulas.
