"Terror" arguments also apply to HSR
High Speed Rail (and super motorway and bridge) infrastructures are easier to target than ET3. For starters, a single 1200 passenger train has 200 times more people on it than a single ET3 capsule. At the same passenger/hour use factor, ET3 has less than 1/30th the concentration of passengers exposed to a localized event (like a bomb). A terrorist cannot target a specific capsule with a high-power rifle or SAM missile) (as they can a train or jet). All modes are exposed to terror, fortunately terror is responsible for less than 1% of transportation fatalities. All this has been discussed in detail by experts on the "International Maglev Board".
