+          tip2: For example, avoid using a via-way restriction if a simpler turn restriction will do.
+          tip3: "* Some restrictions are \"(indirect)\".  These restrictions exist because of another nearby restriction."
+          tip4: "For example, a route with an \"Only Straight On\" turn restriction will indirectly create \"No Turn\" restrictions."
