how should we manage conflict over all issues such as health, safety etc. other than with politics? Sorry but politics has had a bad press in recent years. That’s why so many people don't bother to vote .... politics have been reduced to "who shouts the loudest"...

but then we are off-topic.
Politics is the process of collectively making up our minds, and the nation has collectively decided the 30 mph is the limit in towns – if you don’t take part in the process, you don’t get to choose.
How come some people feel that is not good enough for them? The thread is about laws
you as an individual choose to obey or flout, in spite of the collective
political decision. Surely that is on-topic, especially when that process has yielded dividends, such as a low accident rate comparative to other nations.

But a civilised society needs to recognise that laws require the consent of the governed
Your consent is routinely measured at the ballot box. The parties themselves are democratic to a degree and you could participate in the process if you wanted to. Indeed, by posting here, you are helping to set the consensus, in a way. Yet, up to and until your case is settled one way or the other, the law, settled previously by due process, is that 30 mph is the limit in built up areas, unless otherwise posted. Again, how come some people feel that is not good enough for them? What do you want, the moon on a stick?
