After we hit a deer, disabling the car, I learned that deer strikes generate a significant fraction of body shop work. In reviewing the dash cam footage, the deer was visible well before it lept into the road which was when I first saw it and reacted. So the car could have reacted sooner than I did, but it car did not respond at all. If AutoPilot or forward collision systems could better spot deer and take effective action, it would save a lot of grief and expense. Maybe, eventually, help lower insurance rates for Tesla cars. Also, deer tend to cross at the same places, so mapping these places when they are seen by the cars would also help.
