There is no such thing as a "truly empty road" when you're talking about public thoroughfares. Animals, other cars, and even the occasional pedestrian can all appear at any time, even on a limited access freeway that appears to be empty. The idea that, if the road is empty, "the only person I'm endangering is myself" is bullshit because it is quite simply never possible to know that the road is empty.
Saying, "oh, the road was empty, so it was OK" is a common way of rationalizing the behaviour, but it's not legitimately exculpatory.
Yes, most young males will do something like this at one time or another. When I was in High School I did too. That doesn't make it smart and it doesn't make the rationalization valid.
Furthermore, considerations of whether an individual car is safe at 100mph neglect the fact that a safe speed is not dependent solely on the vehicle, but in almost all circumstances depends far more upon the design of the roadway and the available sightlines as well as the differential in speed among existing traffic. If a road is built such that the sight lines will not accommodate speeds above 55 mph then it simply doesn't matter that the car can safely drive at 100 mph because that's still too fast for the road. For this reason, simply saying that high-speed travel is safe on Germany's Autobahn is not valid as those roads are designed for high-speed travel.
