Mine stayed on for about three and a half months until the corners started curling and I couldn’t ignore it any more. Having it detailed every 2 weeks didn’t help.
I’ve gone 2 1/2 years with no scratches I’m aware of.
What could happen to the lower screen that a film would protect it? If you drop heavy objects on it (metal cup full of water for example), the screen is likely going to crack with or without film. There is very little I can image which would scratch the bottom screen (which has hardened glass) that a film could protect it from (tempered glass maybe). Perhaps a good question to ask would be whether the Porsche screen protectors come with any kind of damage insurance, i.e. if your screen does crack or gets scratched with the film applied, will Porsche replace the screen for free? Somehow I doubt it.
Some icey stare you must have.
If your kids scratch the small glass in the back of the Taycan, I assume they simply shred the leather, scratch all the panels inside, windows, roof liner or glass roof must be in danger to be scratched up too, etc. Are you covering the entire interior in film?
