My next thought was that it was a good spot for reversing around corners and three-point-turns. But, I asked myself, why so many in this particular road? Surely there were other streets in the area that were suitable too.
Today I found the answer to the plethora of learner drivers. I saw one car drive down the side of a property to the car park at the rear. I looked more closely and realised that the building that I had thought to be only 'Thames Heating' premises was in fact two businesses and one was the DSA (Driving Standards Agency). Presumably this is where the learners take their driving tests!
