Well if I build a car with the same track front and rear how can you tell 
what wheel made the track? Second I could argue as a builder that the course 
was not stable enough to withstand the turbulance of the base drag / wake of 
my car at speed and the reason for missing marks. How could FIA contradict 
that? If I was to build a thrust powered anything I certainly would not 
build in any downforce more than needed to maintain control any more will 
just slow me down. I think proof of the tire contact by the methods used are 
not really proof of tires on the ground. Laser ride height gauges might be 
but I could argue there was a very small bump in the poorly prepared course 
that launched the car in the air for some distance. I think the standard of 
all 4 wheels touching the ground 100% of the time a standard impossible to 
enforce and prove. Remember traction control..LOL. Motor racing is not a lab 
experiment with all varibles controlled it is real life stuff happens and I 
think needs to be treated that way but only my opinion and worth 2 cents or 
less no doubt nothing.. FIA would have to disallow any finish by an F1 car 
that ever lifted a wheel during a race and a very common thing if this was 
the standard. The whole big money deal is distressing and seems to be a 
common theme. I think everyone spends 10% more than they can really afford 
and a different number for each so matbe lets get over it. Make any sense? 
Oh well my rants back to bed for me..
