No need lar. Just vary your speed, don't try to drive constant speed for too long. My new car terus sapu 140km/h - 160km/h. And i believe they have already run in the engine a bit at factory.

Logic dictates that you be gentle with the new engines to enable the engine to break in properly

pushing it to the maximum might cause it burn out but i don't see that happening with new cars.

in anycase, what's the harm of being gentle with your new car for the 1st 5000 km?

New car engines are manufactured with very high degree of precision, so the run-in is not so important nowadays. Last time, say 20 years ago, yes, the run-in will be more important because the engineering precision is not so high.

I read my car manual and it does mention a break in period. Specifically for the first 2000km drive at varying engine speeds but don't rev past 3500rpm or drive past 150km/h.

What car u drive??? Usually most car manuals won't recommend more than 110km/h.

Also, you can maybe run-in on a Dyno, the sosphicated way....just make sure u don't end up like this guy...
