Some fair critiques but the tunnel one is way off base. Showing that mass transit is more efficient than cars in tunnels has nothing to do with the question of if building cheaper tunnels for cars will result in a virtuous cycle of commercial investment and development of underground tunnel infrastructure. One of the core theses of boring as far as I understand it is that people prefer cars over subway trains for the most part from a comfort standpoint and so if anything drawing on some of the on-paper benefits of underground rail but transferring them towards passenger vehicles seems like a no-brainer if the economics and logistics work.
