Actually, a semi truck tire is about 127" around. At 60mph, 1m per minute, that is more like 500rpm. For a car tire (80") that would be a little under 800rpm at 60mph. So you are seeing wheels spin aboit 10x per second, which is well within normal perception if you concentrate. Paint a dot on the tire and you would see it spinning around.

Drone blades spin in the thousands, high thousands of rpms.
