Yes, this really happened.
If you're going to spend well over $1 million big ones for a hypercar like a Koenigsegg or Bugatti, you might as well drive them fast. Because if you didn't then what would be the point? Showing off to others is barely an answer. No, these machines have been meticulously designed and engineered to surpass 200 mph and remain remarkably stable while doing so. Not taking full advantage (on the right roads, of course) of these capabilities is almost criminal.
Take the drivers of this Koenigsegg Agera R and Bugatti Veyron Grand Sport Vitesse, for example. They're doing things right by simply going wicked fast, and they manage to keep the hypercars remarkably tame and begin filming at "only" 155 mph. That's just the rolling start, so of course things get faster from there.
And then it happens. The Koenigsegg begins to pull away from the Bugatti, and for whatever reason, the Bugatti driver doesn't try to catch up. By this the speedometer is already over 200 mph, but the Koenigsegg just keeps pulling and pulling. The Bugatti only catches up once the Koenigsegg applies the brakes.
