Earth moves around the sun at 67,000 mph and makes a full rotation once every 24 hours. So why can't we feel the Earth's rotation?

Thank you for pointing out the ill-definedness of "faster": angular vs tangential velocity, as well as frame of reference issues for rectilinear motion.I would argue that the statement in the article: "Our planet is rotating much faster than that" is incorrect.
Rotation is measured in angular velocity (so degrees per hour, radians per second, revolutions per minute, etc. )
If we use the commonly-used units of rpm, earth is rotating at 0.000694 RPM which is far slower than any roundabout would rotate at whilst being used. It's twice as slow as the hour hand on a clock. Most roundabouts would rotate several times per minute which is over 10,000 times faster than the earth's rotation.
Now, if you take tangential velocity as your measurement, that would certainly be more on the earth (at least at most places): the tangential velocity at the equator is over 1,000 mph. But that's a measurement of tangential speed/velocity, not strictly of "rotation".
Cheers,

This is fair IMO.I do not agree to the comparision between smooth motion in car and spinning of Earth. Earth's spinning is a circular motion, which is an accelerated motion, and we should feel acceleration.
