I'd agree in some cases, but realistically there isn't much you can do against people using bombs to blow up bridges - or in this case, hyperloop pylons. It's just not something that you can 'design around'. Designing the pylons to survive if one is blown up? If someone can put a bomb on one pylon, he can put 5 bombs on 5 pylons. Or under 5 cars. Spending your time trying to prevent that kind of thing is futile and an enormous waste of resources. See: TSA
