I can understand the concern about not using the parking brake enough, but what perplexes me is that the resistance can be felt simply moving between P/R and D. Again, that is without taking your foot off of the brake pedal. You shouldn't go from no resistance to resistance just going P --> D --> P --> D
Now, that's not really a normal operation (moving the shifter back and forth multiple times), but it shouldn't matter. Resistance shouldn't be coming and going randomly.
But since some of you folks know way more about vehicles than I do, can someone explain why this in bold is so?
"Tom: Applying the parking brake before you put it in park eliminates that problem. The brake holds the car in place and doesn't let the car roll until the parking pawl jams up.
You just have to remember -- when you come back -- to take the transmission out of park first before releasing the parking brake."

Any idea why they say you have to shift out of Park before releasing the Parking Brake?
