I've always followed the RPM and other guidelines but see no issue going 65 - 75 mph during break in as long as I don't hold the engine speed constant too long as many do during freeway cruising.

There is no mention of 55MPH in the break in period, here is the quote:

During the first 1,200 miles (2,000 km),
follow these recommendations to ob-
tain maximum engine performance and
ensure the future reliability and econo-
my of your new vehicle.
Failure to follow these recommenda-
tions may result in shortened engine
life and reduced engine performance.
. Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
. Do not accelerate at full throttle in any gear.
. Avoid quick starts.
. Avoid hard braking as much as possible.

Good catch- I was wrong on this one but most manuals do state that.

How long would "long periods" be?

I never bought a NEW car, so I am afraid when i get home, driving to and fro' will be detrimental.

I was congratulated by an ocifer that i was the fastest person he ever picked up with his laser. Then he gave me a $500 fine and took my license for 15 days. Eh by the time the notice telling me not to drive arrived at my door my suspension was 3/4 over already and i just didn't drive that weekend. I know for a fact that on a long empty stretch of highway you can get to 157(slightly down hill) fairly quickly.

Some say 30 minutes, other say an hour.
When I drove from Houston to Austin with only 600 miles on my car I was trying to make sure I changed my speed. In the end I did not have to worry because the natural flow of traffic changed, plus the small towns along the way reduce speeds down to 35 for a few.
