Recaptcha is the actual frustrating part.
I have an advice for you: try to make it longer, by taking at least 1 second between clicking on each image, otherwise you may be detected as a bot and even if you
selected the right images, you won't be authorised.
That being said, I never select the poles and only the parts containing the proper traffic light.
The most important part:
If one pixel of the traffic light expands on another selectable part, make sure to click on it.
