I once lived happily a few years ago down a road opposite a school with a cross roads about 200 metres past the school 30mph limit. My next door neighbour was a retired police inspector. Many a time we would be in our front gardens doing the garden cutting a hedge passing time of day having a chat. lost count of the number of RTC,s at the cross roads. We asked how many there had been one year. We challenged what they told us. Apparently not all RTC,s are recorded they changed the way or criterea what is recorded apparently or that is what we were told. Just saying.
