This may sound dumb, but in my opinion, the driver drill takes away from safe driving. At least the way I was taught to perform it. My instructor told me I couldn't say anything that contradicted the scanning method (left-front-right-front-left). I failed first try because I stated something left, then right, but didn't include the front in between. Found myself frantically trying to state BS left front and right and not focusing on what was actually going on.
Your "instructor" was training incorrectly.
I took the week long class and training by Mr. Smith, the originator of the Smith System or as UPSers' call it "All Good Kids Love Milk".
He did not use UPS terminology and his words were different from UPS in some instances.
I also spent a year as the District Safety Manager training operations manager and supervisors how to train using the Smith system.
The scanning process was used mainly in the training on how to keep your eyes moving but it was not a prescribed method to implement as a method.
The 10-point commentary was suppose to be a tool for the trainee to demonstrate that he/she understood and applying the 5 Safe Driving Habits.
The "Train the Trainer" was very successful in keeping individuals from changing the training by mistake or on purpose.
I think it was "too costly" and dropped around 1995 or so. CBT was all the rage.
