Vestibular Memes

Technically correct—the best kind of correct. Humans don't perceive absolute velocity; we feel changes in velocity. That's why you can be traveling 600 mph in a plane while sipping tomato juice like it's no big deal, but slam on your car brakes and suddenly physics becomes very personal. Our vestibular system is essentially just a biological accelerometer, detecting when we speed up, slow down, or change direction. Speed is merely a social construct when you're cruising at a constant velocity.
