> Fire safety seems sub par too. I assume that they are able to meet whatever the relevant safety codes are, but whenever I see footage from those tunnels, I wonder what happens in case of a car fire or some other bad failure scenario. It seems like traffic behind can't back up or turn around or go past. Would the column of traffic ahead have to clear the route for first responders to access? Always been curious about that.
