Observation
One of the most important aspects of driving is your observation, if you don't see it you can't respond to it. So what should you be watching?
When in the car as a Pre-Learner or Learner in the passenger seat why not start learning and practice some important skills in a fun way that develops a natural skill? Pick a car ahead of you and ask see if you can guess what they're going to do BEFORE they even signal their intent.
