It's not always about getting there "faster". I regularly encounter trucks with unsecured loads, drivers visibly weaving, and other dangerous situations. I'm certainly not going to die on some "well this is the speed limit" hill behind them.

Driving isn't some binary situation, you have to constantly predict erratic behavior and react to your surroundings.

You can always go slower and give yourself sufficient braking distance.
