Can't I add some kind of string to the URL of the video to make it start off with the subtitles on and in the "right" language?
We do have the option to have the video start up from a particular time, so why not subtitles too?
And, Google Translate does add those strings to the URL (e.g. http://translate.google.com/#en|nl|), so I don't understand why the same is not automatically happening on YouTube too.

Captions are on by default. You can force the language with
hl=<lang>
but there shouldn't be a need.hl
stands for host language meaning that as long as the host language is set by default there should be no need to send it as a parameter.Try it yourself,
