Do you see any open cockpits in NASCAR or the Nationwide series of racing? ...

David Caldwell of Chevrolet on the Corvette -
"The car is amazingly strong" says Caldwell of the 2005 convertible. "The vehicle structure comes mainly from the center tunnel, which is intgral to the chassis. The aluminum windshield frame is very strong and, God forbid, if the car were involved in a rollover, the windshield frame would support the vehicle. We do not need the additional pyrotechniques found in other cars where a rollbar pops out of the back or some other safety system is required."
Porsche 911 Cabriolet, Mfg Info -
"A Rollover Protection System installed behind the rear seats is extended within fractions of a second if forces indicating the possibility of certain types of accidents are detected. The Rollover Protection System consists of two extendable assemblies which, together with the windshield frame, help maintain the space around the normal occupant seating positions, if the vehicle rolls over."
This discussion has to do with roadsters, hardtops were never on the table lol.
