Sure, you argued against the claim that roads can decrease congestion, the negation of which is the claim that it always increases congestion. Since I only need a single example to prove you wrong I can claim it to be irrelevant to the counter example provided.
Cars suck for many more reasons other than Braess’ paradox, even as it indeed adds to the sucking where applied. Being anti-car should be about more than just misrepresenting facts though, especially when science is in our favor.
We cannot argue that the car brains deny facts and then do the same in return. That undermines the whole argument.
