Aeneid 1.20, 'Tyrias olim quae verteret arces' (which would some day overturn the Tyrian citadel). cf. arceo, ere, to shut up, enclose, prevent from approaching; coerceo, to enclose something on all sides, to restrain, confine. Eng., coerce, to force to act or think in a certain way by use of pressure, threats, or intimidation; compel. Elana Schor article (LaHood: ‘About Everything We Do Around Here Is Government Intrusion’) in Streetsblog on Ray Lahood's speech before the National Press Club: Asked if his emphasis on livable communities was, as Will's column argued, a veiled effort to "make driving more torturous" and "coerce people out of their cars," LaHood was unbowed. "It is a way to coerce people out of their cars," he said, observing that few people enjoy spending an hour behind the wheel to travel to work or run an errand. While every community cannot be redesigned to coax more residents onto transit or bikes, he added, the encouragement of those opportunities is important.
