If your luxury Mercedes didn't come with air-conditioning, no other alternative is provided by the manufacturer for keeping you cool. The iPhone has many (faster) alternative methods for sharing photos. Bluetooth is slow. It's far quicker to share a photo via multiple methods (email, file sharing apps, facebook etc.) over the internet, especially given the file size of average iPhone photos these days.
In the time you've shared just one photo, with one person within 10 metres of you, over Bluetooth, I could've shared half a dozen photos with an unlimited number of people, located anywhere in the world.
I guess you're happy using 15 year old methods of file transfer. You'll be asking for a dial-up connection to the internet next!!
