> What’s more likely, misplacing your car keys, or misplacing your phone?
Misplacing the phone actually. Car keys are either in someone's pocket/bag (then you talk to whoever used the car last) or in a set place in my home. The phone might be wherever I used it last.
Google's Find Device and Apple's similar service mean that you can always determine where your cellphone is. If someone sets a bag on top of my keys, or something similar, the only way to find them is to physically search until I luck out and find them.
So, while I misplace my phone more often, I also find it with less difficulty.
