All that downforce is very suddenly removed.

A race track is a very controlled environment, a road isn't. And there are too many things could very easily cuase the system to loose vacuum making the car literaly fall off the road.
It would not be a catostrophic loss of downforce becaus the air moving through the storm grate would have to be moving very fast meaning that it too would be at a lower perssuer. The same kind of thing was said when the suckers first came out but the big thing was if one of the skirts got riped off during a race the car would loose control. well one day it happend, but the car did not loost control it continued on it's mary way because the air that did migrate under the car was still moving very fast thus at a lower pressure. Did the car loose some downforce yes was the outcome fatal or even dangerous clearly not. They kept running it from what I heard missing a whole side skirt, now maby that story was exadurated i was not alive back then so I can certanly not clame to have seen it but that is the way the story has been told, and untill somone is willing to recreate this event we cannot know for sure, besides even if the car lost downforce altogther would it be any worse of than any other proformance machine and remember that even the supercars with tunnels face the possability of stalling the tunnels creating the same effect no downforce plus the cars with tunnels have a less effective suspeneion geometry. And who is going to be pulling 1.5G turns in the middle of town anyway, people that stupid don't usualy live long enough to get their drivers license and another tid bit of info for you, the first time they got a car to hold togeather with air dispoilers (same downforce system found on modern supercars) the dirver was killed prosumably by the dispoiler stalling out, and how many drivers died when the vinturie tunnels were first introduced by the same thing? Now how many dirvers have been killed in a suckercar NONE to my knowlage, so which one is safer do you think? A tunnel can be stalled out by an increase in rake due to breaking or even a sharp downgrade. Getting the car too far sideways or even a strong crosswind from what I understand can also stall the tunnels and defusers. The sucker is not subject to having its downforce affected by any of those things. Just a little somthing for your brains to chew on.
