Some test centres are in the middle of busy roads. One test (failed) I did was going down roads which had cars double parked in nearly all the streets.Nervous drivers shouldn't be on main or busy roads. Let them use those roads once their confidence and competence increases to a suitable level.
Also sometimes you read in local media that people living in areas near a driving test centre are fed up of driving school cars using their roads for turn in the roads etc. Again, they forget about themselves when they were 17-19 or whenever they passed their test.
