Bulletproof glass, glass roof like the Pope
Jay is saying his car window’s are bulletproof, and that he has a large glass sunroof.
During outdoor public appearances, the Pope uses a popemobile which encloses the Pope in bulletproof plexiglass windows and roof. The glass was deemed necessary after the Ali Agca assassination attempt.
The glass is able to withstand both bullets and explosions.
Metaphorically this means that as an artist he is highly visible however he cant be hit by shots taken at him
