|Most European manufacturers have ~10,000 mile oil changes in Europe, with no problems. So-called long-life oil gets even changed less often, at 12,000 to 15,000 miles.
As mentioned before, in the US the problem is that many people don't use the correct oil, or haven't in the past. For the DI turbo engines and for the TDIs, it is absolutely necessary to use the correct oil: not just any synthetic (even if highly rated for other applications) will do it, for a number of reasons. Oil can get diluted by gasoline, Diesel, or bio-Diesel, direct injection makes a huge difference, and so do the turbos and catalytic converters. The wrong oil in a TDI can easily destroy the DPF.
I know of a number of people who tested their oil for the 2.0 TSI engine, and it was still acceptable after about 8,000 miles or so.
Of course, if you race, drive track events, generally drive like a lunatic, often in hot weather, often with cold starts, often very short distances, often stop-and-go, in the mountains, in the desert or other dusty areas, etc. - that would be considered severe usage, and requires more frequent oil changes according to the user manual, such as e.g. every 5,000 miles.
It is quite likely that 50% or more of owners fall into that category for one reason or another, or for multiple reasons, but just ignore that fact.
