An appropriate definition for "regular interval" will be dependent on usage and application. I already go for a year or more on my garage queens - anything less would be a serious waste based on how I use them. With so many different possible usage/storage parameters and engines/engine combos (stock to a multitude of modification levels), there will never be a single one-size-fits-all best answer to this. The closest you'll get to finding the ideal change interval (best balance between protection and waste) for your application can only come with information from UOAs, but that only works if you always drive the car in generally the same way once you've found the magic balance for your combination.
If you think that a year on the same oil is a crazy/dangerous/harmful suggestion regardless of the application, then you'd likely be very surprised by some UOAs of quality oil that's been used for that period or even longer. Sites like BITOG have a ton of info covering this and other oil topics, some of it is pretty eye opening to folks who have stuck to the antique rule of 3 months/3,000 miles regardless of the oil or how the vehicle is used and/or modified.
