Toyota Land Cruiser: service intervals and pricing

Toyota is way behind on industry standards on service intervals and the updated Land Cruiser 200 is a good example, with service intervals of six months/10,000km, which is well behind other vehicles in the same class. Many of the European diesel rivals have had 12 month/20,000km service intervals for well over 15 years with no issues. I am wondering whether Toyota is over-servicing the vehicles, or if their vehicle technology is out of date. I have a fleet of Toyota work vans and the 10,000km service intervals are a real pain. Some of the diesel Iveco commercial vehicles have service intervals over 30,000km.
