It's a ridiculous imposition anyway. One can see a reason to compensate for incompetent councils that put schools on busy roads, but not elsewhere. 30 mph has been fine for decades. A road is supposed to be a dangerous place, people ought not expect to be wrapped in cotton wool and remain in perfect safety all their lives impinging on others in the process. There ought to be a sanity check for those who want to get into power and pass this nonsense. It is a prime example of how society is being made as ludicrous thing these days. 20 today, 10 tomorrow, 3 the day after. When are these people going to be prevented from ruining everything ?
