What about putting happy drugs into all alcoholic drinks? Something which makes people non violent?

Hmm, sounds like YOU might have been on the happy stuff during my talk. The aim is to create a social nudge not a liquid kosh! Still, nice try.

How do you put a "shove" policy forward when your government just has minimal appreciation for design such as in South Africa?

Simple. Get a meeting and don't talk about design. Talk only about their problem and how you can help.
