Re: Luckily
until I see some signs for where I want to be and follow them
Which is fine, right up until you want to navigate across Birmingham..
(Even though I was born in Brumagen, we left there when I was five. So I've not had an opportunity to aquire knowledge about the various boroughs[1]. So who knows if Selley Oak is near Kings Norton? And, unlike London where the roads signs point you to not only the next borough but also to the ones beyond that[2], in Birmingham they don't appear to.)
[1] Or the delightfully idiosyncratic accent.
[2] Plus, having grown up in London, I have some idea of the layout of the various boroughs. In the proper, civilised bits anyway - I know very little about Sarf Lunnon.
