Oh, yeah, or at least not give a hoot if they run over some squirrel or rabbit, or possum. I've seen that plenty of times around these parts. Particularly the yahoos in pickup trucks seem to care the least, in places like Lawrenceburg, IN and surroundings. They'll swerve plenty to avoid a skunk or a deer, though.
One time, I was at work at a place that sat near a rural highway. My cubicle had lots of glass to look through behind me. People there drive 50-60 routinely. (I think the limit was at least 50, if memory serves.) These ducks constantly crossed that highway. For some reason, they liked to waddle over to our parking lot, then waddle back across to a pond on the other side. Everyone typically stopped and waited. This one day, I happened to be looking at them doing their typical slow walk across, when this semi truck comes barreling down. He had to be doing 70 at least, and he slowed down not one iota. Disaster? No. He didn't hit a single duck. I now know those things are just messing with us, showing off on their crawl across the road so everyone has to stop and look at them. Oh, yeah! When they knew that mass of metal was not going to play their game, man, you should have seen how fast they could take to the air and scatter. Hahaha! The only casualties were a few feathers.
I did hit a bird with my windshield once. It was the freakiest thing. I was going about 60 on the highway, and this dumb thing just comes in gliding out of nowhere, prancing in the air, going the same direction I was (which is what makes it not seeing me so puzzling). I remember it looking back a split second before the splat, and then seeing the body on the road in the mirror, with a shower of feathers slowly joining it. Like the cat, this all happened so fast, but I remember it almost in slow motion. Weird. Lucky for me, it hit on the passenger side, because it made a non-transparent mess.
