Given the fact that air resistance is increasing quadratically with speed, that fast cars are loud, that accidents cost everybody in a socity time and money and that we have even more to expect in form of climate change not having a speed limit seems like a very radical political position. It doesn't seem radical, because it has been "normal" for a long time, but it is forcefully irrational.

Nothing against a little bit of irrationality. I am jumping into the sea or lakes from cliffs, bridges and cranes. But this is a danger to myself and not to others. Also I check beforehand how deep the water is.
