if a bug is flying around your car while you’re driving 60mph on the highway, is the bug flying at 60mph?

So there is a concept in physics called an “inertial reference frame”, which is basically a way of saying that everything in a certain location is travelling at the same speed in the same direction, it is as if there is no movement at all. This is why you do not feel the rotation of the earth, despite it rotating at thousands of kilometres an hour.
Another way of visualising it is being on a train and throwing a ball. Within the reference frame of the inside of the train, everything is still, so throwing the ball behaves as it would if you were on the ground outside of a train.
