Correct. The rings are sealed within the first 20 miles...the harder you drive the car the better they'll seal. The rough honed engines are a thing of the past and you no longer have to baby an engine when you get a new car.
In fact, vehicles that are babied are noticeably slower and perform worse than cars that are broken in more spiritedly. The reason why the break-in process is still the way it is is because of liability reasons...nothing more.
