I suppose it depends on the team in general then. Even though the coach is there to provide general game strategy, it is often more efficient, even with a coach, for the driver to make decisions him/herself instead of only listening to the coach.
The time it takes for the coach to make a plan, communicate it to the driver and for the driver to comprehend the plan is inefficient. As a driver, I find it far easier to make decisions WITH the coach instead of waiting for the coach’s decision.
Once you practice enough and get enough experience, the controls for your robot should feel like an extension of your body (to use lame cliches). At this point, the game is far less a test of driver skill as much a test of decision-making and foresight.
