Yes, the New York City subway. Famous for being unaffected by hurricanes and other inclement surface weather. Immune to flooding. Truly. https://t.co/mZHkjALfVe Quoted tweet from @elonmusk: @JohnnaCrider1 @stats_feed Underground tunnels are immune to surface weather conditions (subways are a good example), so it wouldn’t matter to Hyperloop if a hurricane was raging on the surface. You wouldn’t even notice.
