We have squirrels running across the road all the time. When my kids were learning to drive, I had to make it absolutely clear to them that their lives, and the lives in other cars who might happen to be on the road with them, are more important than squirrels.
Run over the squirrels, if that’s what they choose. They have a dreadful habit of waiting by the side of the road and then dashing in front of you at the last minute.
Taught my children the same thing. Don’t swerve for a dog, deer, cat, squirrel, etc. and wreck the car or kill someone by hitting them. Ever.
