There is always the autobahn. If systems like that existed endangered there could be incredible time savings. A related question of mine is ‘If cars can go so fast why do we not find ways to raise speed limits while keeping roads safe?’
Why are assault weapons so difficult to own in Europe? They make them in the US and you can own them there. As to your question - I’d like to refer you to physics. 2000 pounds of metal moving at any speed can kill pedestrians easily. More speed means more energy. Increasing speed limits consumes more fuel, wears roads more, pollutes more tire and brake dust, and of course kills more. We should not make things more co…
If the cars move faster, they will get off the road faster. This means fewer vehicles on the road and the distances between the vehicles will increase. It is a linear effect if you adapt a flow equation to vehicles. Here is the equation off the top of my head:
V1*D1*L1 = V2*D2*L2
V is the average speed, D is the linear density, L is the number of lanes. If you care about safety, you want D to be as big as possible so that vehicles do not have distances between them reach 0. That implies higher speeds (or more lanes, but that is harder to do).
Finally, the gun analogy is inappropriate. It is essentially saying “the data contradicts our conclusions, so let’s shutdown any rational thought that might question our conclusions”. This kind of thinking is backward and should easily lead to nonsense such as the rationalization of square wheels to give an example of the absurdity it allows. Interestingly, much of what you said could also be said in defense of the forced adoption of square wheels.
