The width of the front wings was limited to the inside edge of the tyres by the regulations, ostensibly to prevent the cars becoming unsettled in the turbulent air in slipstreams. This was considered both a safety measure and was thought to facilitate overtaking.
And you have to admit that today, limiting airfoils to two planes would save HUGE amounts of money as there would be very little to be gained by the endless hours of simulation and testing that prevail now.
IMO, each year, the advances in technology brings on a reduction in the importance of the driver to the overall result. As far as I am concerned, that results in a lessening of the stature of the WDC.
If out-and-out tech is your desire, why not do away with the driver entirely and have the cars be RPVs with unlimited tech. Performance would improve dramatically.
