Dizziness comes because of acceleration: a change of speed in time.
The angular velocity the Earth spins with, is constant. Is like not feeling that the train is moving while it is going fast but steadily.

You have special fluid in your ears which helps your body to regulate balance. When you spin yourself dizzy in a chair, that fluid acts as an accelerometer and tells your brain you're accelerating in a specific direction and your equilibrium is thrown off.

But here on Earth you don't notice it's motion because of it's size and the fact that you're equilibrium is calibrated such that the motion of Earth is normal.

In the absence of this motion, such as outer space, the body becomes incredibly disoriented.

Because it spins very, very smoothly and really quite slowly -- only 15 degrees per hour.

We only get dizzy when our rotational speed CHANGES drastically. That causes the fluid in our inner ear to spin around RELATIVE TO THE EAR which throws off our proprioception.

It is not just change in speed. One the answers alluded to it...15 degrees per hour is very slow. Imagine turning in a circle once every 24 hours. Will that make you dizzy? Nah. Not enough centripetal acceleration to slosh the fluid in your semi-circular canals in your ears into weird places.

Do you get dizzy if you spin yourself all the way around once every 24 hours?
No?
Well, then you won't get dizzy riding on the earth ... even if you're standing at one of the poles, where the earth is spinning you directly around your vertical axis.

Now, if the earth were turning at 100 revolutions per minute (instead of .0007 rpm), then you'd probably get dizzy.

You would be surprised how many dizzy people there are even if the world did not spin!

Because we're spinning right along with it.

Because the planet is so big compared to us that we don't even feel when it is spinning. :-D
