title: Get current position in Google Maps JavaScript API v3 and get the dot to follow me without user interaction
body: <p>I am assuming this is not possible or advisable due to the nature of the web but I will ask anyway.</p>
  
  <p>I know I can get a user's current location and centre on a map using the Google Maps JavaScript API v3. I can even get it to show a dot for where the user is currently located.</p>
  
  <p>What I really want to know, and my client is asking for this, is can I get the dot to follow the user around without user interaction (ie.. the user does not interact with the device, the dot just moves when the user moves.)? All I can think of is that I would need to add a timer event to continuously check the current location and update the dot. I don't feel this would be best practice.</p>
  
  <p>I have found lots of posts on how to do this in an android or IOS device but not on the web.</p>
  
  <p>Any pointers and info will be greatly appreciated.</p>
  
  <p>thanks
