Windows for drags

I know this was brought up “Back in the day” but it’s obviously not “back in the day” anymore. Is a window net for driver sufficient as far as side glass goes? 

I’d REALLY appreciate an official ruling on this one.

The rules said:

A: We realize that the NHRA rulebook has a few issues when it comes to this event. The following rules may be ignored if your car runs slower than 11.49 E.T.:

• Windows must be rolled up during drag runs (if you don't have windows, you'll be required to wear a full-face helmet).
