This is a quote from the author of the book Talent is Overrated:
“When we learn to do anything new—how to drive, for example—we go through three stages. The first stage demands a lot of attention as we try out the controls, learn the rules of driving, and so on. In the second stage we begin to coordinate our knowledge, linking movements together and more fluidly combining our actions with our knowledge of the car, the situation, and the rules. In the third stage we drive the car with barely a thought. It’s automatic. And with that our improvement at driving slows dramatically, eventually stopping completely.”

This aligns with the idea of processing conscious information slowly, even if the 10 bits a second is off by a factor by 2 or 3 times or even a factor of 10 it seems correct.
