What could I do during lockdown? Some research or study? Another formal qualification? I was verging toward a doctorate at Nottingham Trent University, where I spent an interesting hour with their psychology professor involved in redesigning the DVSA theory test.
Topics of mutual interest were:
At what point in traffic density does a signal become important, then distracting?
Should mall and supermarket car parks always "force" reverse-parking?
Does a stranger in the car affect your driving test performance?
Do aids to driving just make us more lazy, and so risky?
The uncertainties of a post-Covid world mean I doubt serious study will make financial sense in the foreseeable future. But never say never.
