[I *know* that's not a deer...]
My ‘96 jetta made oil pump noise that deer fled in a panic from.
It was high pitched, bare bleeding edge of human hearing.
Deer would hear this thing coming and panic.
I always had a laugh about that.
My current car does not have that noise.
I’ve had deer mob my car and snuffle it as I was trying to exit my driveway.
It is disconcerting to sit in your car and have deer see you but not give a crap, they were busy sniffing your car...
