Aerodynamic advantage? On a Top Fuel Dragster?
Are you kidding me? Why should there be ANY rules on how body lines are configured on the pipe racks?? They are in that rare air stratosphere of some of the few racecars on the PLANET that look EXCLUSIVELY like NO OTHER CAR out there... With the exception of wing size and placement in relation to the tires, I say let them come up with any body style they want.
Now- as far as a safety improvement: seems to keep everything EXCEPT FIRE from coming into, and staying, in the cockpit... And in Antron's case, the spraying fuel line probably had a lot to do with how much the driver was engulfed. Maybe some more tunnel time to create a positive airspace in the driver area is needed, to blow flames out of the cage/ pod area... But I bet the wrap-around was good for keeping bits and pieces away from the driver's head- which I assume was DSR's intention when they said the semi-canopy was for "safety purposes".
I am torn about the ruling coming down when it did. Yes, I would think that a post-season change/ redefinition of the rules would make it fair for the DSR cars, but on the other side, if something catostrophic happened between now and the end of the season, this would be one of the first places to be screaming bloody hell (and using that same ESPN360 clip as the example) about how someone at NHRA Tech should have seen this incident in Reading and should have done something then. And since NHRA gave the bodywork its blessing, that would put them on the hook for some of the liability, similar to being partially responsible for giving the OK to the JFR cars to be partially heat-treated...
I'd hate to have to write the rule book...
