I know in qualifying drivers are at their max and on the limit, come race day though, how close are they to the limit of the car and to their own ability.
They are often lauded for their consistency but if they are not close to the limits then that consistency doesn't seem as impressive as one would think.
In racing games I am generally on the limit at all times but I am hindered by the car, the extra weight of fuel, tyre wear, dirty air, etc.
Are real drivers knowingly holding back and keeping a bit in reserve or are they indeed limited by their equipment.
