No, the main skill is planning. Whether or not you're endangering other people it's hard to cover lots of miles quickly on roads with other people. Nobody who's serious about a good time is going to be on a crowded road. It's a waste of time.
You have to balance your route planning between weather, peak commuter hour, shortest route, fuel stops, speed traps, etc, across a few thousand miles and a few time zones.
The biggest risk to "others" is that when traveling much faster light traffic you have little margin for error if someone in that traffic does something dumb.
