There has been some criticism of F1′s dependence and spending on aerodynamics and this led to some thinking about the re-introduction of ground effect technology.  But this proposal has been unanimously vetoed by the F1 teams on the grounds (no pun intended) that the same could be achieved by restricting aerodynamic dependency.  In our opinion article we have talked about this.  Ground effect essentially requires a shaped under tray for the car and moving to this means that all teams will be equal when the rule comes into effect and so the defiance.  Some lessons are never learnt.
