Most roads aren't an issue, the street I use is untreated and I can pull off 3 point turns and reverse into a bad, no problem. The big issue is getting from my house, down what was a dirt track then up a few rather steep hills, the first being a single track 16% incline that is currently looking like it has been ploughed. It is hard to keep your speed up and wheel spin down when you have to weave in-between pot holes the size of a child while trying to stay on what is left of the road surface and hoping nothing big comes round one of the many blind bends.
Once I'm clear of single lane hell, it is less of an issue. But then you live in Norfolk, the biggest hill you have down there is a curb stone.
