I have seen people swerve to hit them like it’s a game.
I try to avoid killing any animal with my car if I can help it, except for poisonous snakes.
I hate people who would deliberately drive over a turtle. I like turtles, although I would not want a snapping turtle take a bite out of me. I have carried little turtles that were in the middle of the road. Once I came upon this big old turtle in the middle of the road. I stopped and got out of the car (it was not a busy road). As I approached the turtle, it made an angry hissing sound. I backed off and fortunately I guess I annoyed the turtle enough that it started walking away and it got itself off the road.
