One interesting thing about riding a bike is that to turn right, you must initially turn the handlebars to the left (called countersteering). This is subconscious, not explicitly taught and virtually everyone disbelieves this at first when told. But it's something that needs to "click" in order to ride a bike. It's the reason it is so hard to ride a carnival trick bike with a gear added to reverse the handlebar/steering relationship; you don't consciously know how to change your input. There's even some videos by bike youtubers that learn to ride a bike with reverse steering, including the subconscious countersteering part. When they switch back to a normal bike, it once again takes time to relearn.

To relate this back to the comment thread, people don't even always know the full extent of what they have learned.
