I see.
Been guided is not aiding the driving of the car, the driver is in full control unaided in the control of the car.
While they are heavily guided they sort of have to be, I mean the pit wall has all the data and the strategy, things change based on other drivers, in the cockpit you have no idea whats happening. If a driver needs to coast for a bit to secure a win instead of pitting (Dan at spa). Or waste the tires to come in earlier they need to know that.
To what extent do they put this rule in force, drivers are going to go out there blind, it will make for interesting racing but it sort of makes racing a pot luck situation, how does a driver know if they will need those tires in 10 laps time or not, its going to be more about chance and whose decisions happen to fall in line with luck of the day.
