Dofus me left my iPhone X on the roof of my car after filling up. It has a el cheap eBay silicone case and Spigen glass screen protector. Drove approx 10 minutes from the gas station and the traction from the silicone case kept it on the roof. Accelerated to 60 MPH and off it flew. I heard a thud when it hit my spoiler and i saw a blue object in my rear view mirror. Didn't realize it was my iPhone immediately, but after a few moments, i patted my pant pocket and ohh crap, that was my three day old iPhone X!!! Made a quick u-turn in the middle of heavy traffic, parked, walked thru gridlocked traffic, and found her laying face down on the asphalt. The glass screen protector was ground almost thru at the corners, but did a very good job at protecting the phone. Only small scratches on three of the four corners of the glass.
