I won't say what cars I own but I do have the front of each covered in 3M Clear Bra material - it makes no sense not to and leave the paint open to damage from road debris and wind-driven sand and dirt.
I'm on my third windshield on one and my fourth on the other, thanks to the aforementioned wind-driven debris not to mention rocks thrown up by other vehicles.
Perhaps in other areas windscreen damage is rare, in many areas of the US the average windshield lasts two years at most and windshield chip repair is done perhaps twice a year if not more often.
For example:
CUSTOM CLEAR BRA FILM in Centennial, CO
XPEL Clear Bra installation - Los Angeles, CA
Paint protection film applied is typically at least $2000 per vehicle.

It's also quite common for Jeeps, including the Grand Cherokee you cite, to have film applied as well.
