<p>We disable contraction hierarchies for car as we currently have not implemented CH with turn restrictions. But disabling CH now falls back to <a href="https://github.com/graphhopper/graphhopper/pull/780">a still fast enough algorithm</a> that supports turn restrictions. For the others vehicle profiles: there is no reason yet to not use CH.</p>
