I can see both sides of the argument but for the life of me can't see why anyone is getting particularly angry.

Was in Odisha, India, recently and built up areas in Bhubaneswar are 20KPM.

I am a driver, some of the road I drive on regularly have been 20 for a long time. Some of Pen-Y-Lan road now being 20 is the least of my worries as the local authority has decided to to completely mess up the turn onto Colchester Avenue - the right hand turn is so disconcerting for oncoming traffic it causes a lot of anxiety for drivers who don't often drive there.

Surely we will end with with a few roads reverting to 30 but built up areas where there are schools etc, remaining at 20, which I think is sensible.

But in these polarised days nuanced opinions are sadly becoming extinct. I feel I need to pick a side and defend it and get angry with anyone who disagrees with me.
