I live in a council area that has a 20mph limit on residential streets, the more main roads are still 30. I don't get the angst if I'm honest, there are a couple of roads that I use that I wonder why there is the 20 limit but you just deal with it.
It personally isn't something that is that important to me in terms of voting decisions, it wouldn't be the issue that gained or lost my vote, though I would wonder why a local candidate had it in their manifesto to overturn it.
