Otherwise, the rings won’t burnish the cylinder walls properly, and the engine will have high volumes of blow-by—which means excessive oil consumption and shortened engine life. If you’ve ever seen the car jockeys who drive new cars off the end of the production line into the storage lot, or the transporter drivers zipping up and down the car-hauler ramps, you’ll realize that this all-important step has been performed for you many times. If you’re installing a new engine, simply give it a few seconds of wide-open throttle in a high gear. For the first thousand miles, avoid constant speeds and throttle settings. If you commute in normal stop-and-go traffic, you’ll be fine. I advise against cruise-controlled sojourns across Nebraska.

I get what's being said here... but the thing is, it would seem that running wide-open throttle in a high gear would result in redline engine rpm and very high road speed. And this kinda conflicts with the manual's advice to avoid 4500+rpm, full-throttle, very high speeds, etc.
Unless the expectation is that you floor it in a high gear (just for a few seconds) at a fairly low rpm... but would that still accomplish the intended?
