My 37 Ford would get 60 PSI oil pressure cranking the starter at 100 RPM (about 1/3 of the cranking speed of a modern car) after 5 seconds.

Ignition off, cold engine, 74 year old technology, no oil filter, ancient parts.

You start a modern engine and you have oil pressure faster than you can say "yes". Modern oil filters have check valves that keep them full of oil.

The only problem I see with lowering the fast idle speed Robert, would be you also need to reduce the enrichment or you might get your plugs loaded up with raw fuel.

Not sure if the Insight controls fast idle speed and mixture in a coordinated way.

I just drive it away quickly and use the fast idle to propel the car through my neighborhood at 25 MPH. In your case (with a manual) you have the choice of using a higher gear to keep RPM lower and extract more work out of the fast idle-cold enrichment time period.

That is what I do with my VX, keep the RPM low in the first few tenths of a mile, which also helps with cold engine fuel consumption.
