It's time for my invention, which is yet to be developed, but consists of making the oil sump like a propane hot water heater, much like the ones found in motorhomes. A thermostat would control the temperature. A small LP tank would fuel it, or you could go LP all the way, for both the heater and the engine's fuel, which will add the bonus of clean running oil. The heater not only keeps the oil at an optimal temperature (can run lower temp when parked a long time and hit a boost button for a quick warming before startup (or on a timer), but also the exhaust from the LP heater is directed to warm the entire engine bay and perhaps shoot back over the tranny on it's way out.
Now, once we get rid of cold start wear, the manufacturers can make thinner bearings, since most wear is eliminated and they don't want the vehicle to last too long or it will hurt sales.
Of course, even with winter start up wear here in Michigan, our engines outlast the bodies, so the average Joe just doesn't care that start up wear is the major wear factor. It won't affect him anyway.
As for me, well I plug in an oil pan heating pad in winter.
