The aircraft is flying faster than it is taking you to process the changes that are occurring during the flight. There are a number of things you need to process as you fly, from radios to maps to situational awareness. For less experienced pilots, or when you have passengers than are pointing out all sorts of shit, this can take time. During all this time the aircraft is moving and the condition is changing. You need to not only know where you are now, but where you will be in the future. If you lose this, you find the aircraft getting to places faster than you can prepare for, and that can be nasty. To relate, it's very similar to driving a car for the first time. There seems to be so much more to check, from mirrors to gauges to the road. The reaction for new drivers is to slow down to give yourself time to catch up. Another analogy would be sports. If you play a team sport with those that have played for years, you can find yourself reacting to things after they have happened. This isn't because you don't know what to do, but more so because by the time you've figured it out and acted, the event has already occurred.
