Caution:
At any given time, expect the unexpected...
Even if your car is tip top, road conditions are fine, no other drivers are around, Wham. A deer or other animal can come thru your windshield and kill you. It can easily happen. Just be very careful, and watch out for wildlife. It is easy to forget about.
I wrote off a deer and my Subaru once. I wasn't trying to set a new landspeed record at the time thank god.
