title: PyDrive "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup" despite logged in and authenticated
body: <p>I have a bit of python code using PyDrive, to download files from a shared google drive folder. It looks like this.</p>
  <pre><code>from pydrive2.auth import GoogleAuth
  from pydrive2.drive import GoogleDrive
  
  gauth = GoogleAuth()
  gauth.CommandLineAuth()
  
  drive = GoogleDrive(gauth)
  
  file_list = drive.ListFile({'q': &quot;'XXXXXXXXXXXXXXXXXXXXXXXX' in parents and trashed=false&quot;}).GetList()
  for file2 in file_list:
      string = &quot;'&quot;+ file2['id'] +&quot;'&quot; + &quot; in parents and trashed=false&quot;
      file_list2 = drive.ListFile({'q': string}).GetList()
      print(file2['title'], file2['id'])
      for file3 in file_list2:
          file3.GetContentFile('/data/' + file3['title'])
          print('downloaded: ', file3['title'], file3['id'])
  </code></pre>
  <p>This downloads roughly a TB of data in many tens of thousands of files. (The original file link is not XXXXXXXX, I just added that to avoid using the actual file ID in this example). The code works great for like the first 25k files, when it suddenly fails with</p>
  <p>code: 403,
  message: Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.</p>
  <p>I sign in successfully with OAuth and my google drive api is enabled and it has a quota of 10,000,000 requests a day (far more than I am using). Why does it think I am still using an anonymous account and hitting me with this error?
  It is my understanding that because it is a file that I have in my shared drive and because I am signed in I shouldn't be encountering this, whats up with that?</p>
