Why do they cut holes in window tint in south east Asia?

Our lead instructor at the Tint Academy is teaching the first ever courses in south east Asia through Manila and Cebu 

 

Adam found out they cut giant holes in the window tint in most vehicles to improve visibility at night 

 

but why do they do this? (Watch the video above) 

 

they mainly do it because purchase dyed film, which does not hold up under the extreme heat and sun and begins to fad and becomes 

 

drivers will cut holes in the tint once the film becomes faded and distorted so the visibility through the film is impossible to see!

 

but why not use a high quality film like a nanoceramic or ceramic film with higher heat rejection?
