He might be a smart guy but this tunnel idea is completely idiotic. Digging tunnels is easy. Digging tunnels that can carry vehicular traffic, that meet safety standards, that don't disrupt the buildings above them, that don't shift or collapse due to seismic faults, that don't interfere with or collide into other infrastructure is hard. If tunnels were easy, if tunnels were the future, the clusterfuck of crazy that is the Seattle tunnel wouldn't have happened: https://en.wikipedia.org/wiki/Alaskan_Way_Viaduct_replacement_tunnel https://en.wikipedia.org/wiki/Alaskan_Way_Viaduct_replacemen...
