Earlier quoted context omitted.
In practical terms speeding actually makes very little difference to your journey time. Eg if you have a 100 mile drive on a 70mph road and you drive the entire way at 85mph your reward is saving about 10 minutes on a 1.5 hour trip. The downside risk is getting charged for speeding and being delayed for much more than 10 minutes. I've never though the cost/benefit shows it to be particularly worthwhile.
There are exceptions to this though. If you're driving through Europe at night you can easily spend most of your trip on highways safely going 180kmh or faster, saving you many hours on longer trips.
This is why if you spend much time over that line, you will find that people will seemingly jump out from behind an LKW and cut you off. It's not because they're idiots or trying to intentionally crash, but rather they most likely completely misjudged your speed due to the innate human capacity for judging speed.
Therefore I've been told that while it's not against the StVO to drive over 130, doing so is a liability risk.
