The world sure would be easy if we could just label what street designers do as "engineering work beyond redoubt" and every opposition as "[political] activism". But of course it isn't. It is long known that making oversized streets encourages speeding. Yet they keep designing them oversized. It is well researched that "sharrows" do nothing. Yet they keep painting them. Their work is not that of engineers, it's work from guidelines that are of course the result of politics first and foremost.
