It is high time that the FIA took driver weight out of te equation as a performance differentiation in F1.
The cars minimum weight should be set without the driver.
Then the driver and his equipment's weight should be set at say 90kg with all competitors ballasted to be equal.
(Pedants welcome to substitute mass for weight above!
)
Hulkenberg being excluded from drives on this very basis.
