i have to say concern trolling about ip violations seems pretty unconvincing when it comes to warfare. what self-respecting military is going to be like "nah, my bad, you're right. gunpowder was your idea"
@GlennLuk You said that his analysis is flawed (which it is) but didn't actually explain how the expressways aren't overbuilt, just analogies with hsr and metros
@GlennLuk You are right about metros and hsr but wrong about expressways. It is actually overbuilt. Every yuan that goes into it could have gone into the other two. Most Chinese people I know actively avoid using it due to high tolls and instead use the old highways
