It wasn't because people was driving them hard before 1000 miles mark. From what I read when I was researching the main cause was the ECU tune was too lean. Someone already mentioned this but the factory will test drive the car pretty hard before shipping it out. I'm starting to think the ringland issue is more likely to happen to people that have aftermarket tune and might have mess up somewhere in their map since there's more reports of ringland failure on STI with aftermarket tunes.
I think people just need to use common sense when driving any car. I will most likely to not have any problem not going crazy with the car for the first 1000 miles so I won't mind following the manufacturer recommended break in period.
