Yes, but consistently we get people just on this forum who don't know of its existence, and who struggle to go around bends. There must be millions of riders out there who are taking bends, but who dont actually know how - they are relying on their instincts/subconscious. But then when they find themselves deep in a corner and running wide, it's their conscious mind that's in control, they panic and do the wrong thing because their conscious mind doesn't know how to use counter steering to tighten up the line, and they end up in the ditch. Good teaching should not assume any prior knowledge. They should teach vehicle control from the ground up, and that includes how to steer a bike.
