At the same time having a double decker diffuser (as with the Williams and Toyota cars) is in effect creating a Venturi tunnel underneath the base of the car and making the car basically hug the track surface. Isn't it by extension a modern version of the dangerous ground effects cars of the 80s? The big thing though is that being where the diffuser is on the cars, and given the aero development through the times, its much safer in cornering than those monsters ever were. I was always fascinated by ground effects, and would welcome to see safer cars as a fan once the level of understanding was significant. As a fan, I'd like to see these 3 teams keep their positions and others try to catch up with this state of the art, but if you respect the letter of the law, these are in essence ground effects cars which have been banned for 20 odd years.
