I wonder how many of those who don't protect their cars plan on keeping them beyond the loan, beyond 3 years, are leased cars, or just don't care about such things as bad looking finish. I see quite a few cars, especially SUV's that have really awful looking paint, or appear like they were never washed. I realize some cars aren't designed to last more than 2-3 years so it is justified. But spending $90,000 for a Tesla Model S, even my attitude has changed on keeping it as nice in year 8 as in year 1. It's not just the cost, but the fact that Tesla keeps getting better with software updates too so I have no incentive to consider replacing it with the latest Model S. The jury is still out on my Model Y but I did a similar PPF + Ceramic. There may be some benefit to having better features such as a driver's instrument display like in the S in the future. I've never been a big fan of just the center display as some are. I probably won't keep the Y as long as the S but time will tell.
