Your worldview

But what if my mind isn't logical ?

Relax.  Artists and humanities teachers can drive.  Stressed people, new parents, the recently bereaved.  Cars and roads are designed for everyone to stand a decent chance of reaching a safe standard to "go it alone".

Just because your think you're scatterbrained, or a butterfly, or have ADHD or a spectrum disorder, doesn't mean you can't manage the UK roads.  Their rules may be logical but, with a little practice, you'll find you don't have to be.  Just work at following a small number of patterns (or routines).
