People keep saying "we can't just hang out in limbo having voted to leave but not activated Article 50."
The terrifying thing is, you totally could.
Imagine a world where Britain just never either rejects the referendum or activates article 50 because nobody has the political will to do either and just stays in the EU, technically with the full authority and power of a member state but with no real ability to commit to anything or take any posts because they are kind of sort of on their way out.
It could happen!
After reading a bit on the recent debates:
How can a goddamn prime minister, a person voted by his people to represent his country internationally and lead his country to prosperity, just openly (blatantly) wave away everything to his successor in the face of one of the biggest threats to his country? What the hell is this? I don't understand this at all (not overly familiar with British politics).
And if he really plans to do just that, sitting things out, will the UK really have to wait and until the next votings before anything will happen? Can't the current cabinet fall (as they aren't doing a thing seemingly) and allow the people to vote for a new leader who want to lead asap?
Cameron opposed leaving the EU. Now that the vote was for leaving, he doesn't want to be involved with the process of leaving (as he correctly observes it to be a terrible idea that will be impossible to execute well).
If there were people on the Leave side ready to jump up and take charge he probably would have resigned immediately. The fact that he's waiting four months to do so should be clear evidence that in fact nobody actually wants to take responsibility for leaving the EU.
