title: Google Maps Api straight (shortest) route
body: <p>I am currently trying to find a way how to get a straight route with Google Maps Api V3.</p>
  
  <p>I already managed it to use geocode and the directions service to get a route from point A to point B, including two alternative routes. I also experimented with "No highways" and "No tolls" but nothing appears to solve this problem entirely...
  At the moment I check the three given routes for lowest miles but this has to be proven not really to be the shortest route.</p>
  
  <p>I am <strong>not</strong> searching the fastest or quickest route but just a <strong>straight route with</strong> as <strong>low miles</strong> as possible.</p>
  
  <p>As I did not find <strong>any</strong> thread by using google explaining something like I need I ask you. Maybe somebody has a solution here...</p>
  
  <p>P.S.: I also can't use the "Pedestrian Mode" as this is used as a navigation help for our local fire trucks when our mounted navigation systems do not work again.
  This is also the reason why we need as low kilometers as possible - when driving a firetruck round here the fastest route is 99% the one with lowest miles but the Api won't let me decide that and insist on using principal roads</p>
