Engaging in your driving
This is me playing my F sharp scale on the piano.
Now I have practiced this for years and know it by heart.
I reduced my speed to 60 notes per minute or one note a second.
Here I am really struggling to remember what I am doing.
It is the same when driving, one of my customers was really struggling with another instructor as they were going 5 mph and the engagement was too low to be of benefit to her.
Lets say for example that they reduced the speed limits on motorways from 70 mph to 30 mph, it would be so hard for motorists to be engaged at a slow speed they may switch off and have more collisions.
